Follow-up cleanup on the profile-builder refactor.
AgentProfileBuilder::build now borrows instead of consuming, removing the
builder.clone().build() dance at all seven call sites. Deletes
with_command_timeouts, which had no caller but its own test, and the
with_summarizer constructors on all three profiles, whose only remaining
caller was each profile's own new().
Replaces the fifth copy of the profile-kind match (guardrails.rs) with the
builder, and swaps the parity matrix's hand-maintained provider list for
Catalog::effective_agent_profile so a new catalog provider cannot silently
skip the matrix. Collapses web_search_provider_test! into a secrets = arm
on provider_test! and uses EnvVars::BRAVE_SEARCH_API_KEY over a literal.
Drops the Brave key from the Ask Fabro session: AskFabroToolAccessPolicy
denies web_search, and both tools() and the prompt are filtered through
that policy, so the vault read only registered an uncallable tool.
Makes NativeToolOptions::for_profile match exhaustively so a new profile
kind must state its timeout, restores Anthropic's borrowed prompt sections
and Gemini's static prompt (placeholder substitution rather than format!
over 110 lines with doubled braces), and introduces WEB_SEARCH_TOOL_NAME
for the registry lookups that keep tool availability and prompt guidance
in sync.
Updates the product docs, which still described web_search as always
registered and as erroring at call time when unconfigured.

Chat Completions only emits the trailing usage chunk when the request sets
`stream_options: {"include_usage": true}`. The openai_compatible codec never
sent it, so providers that follow the spec strictly returned no usage at all
on streamed responses. Every message came back with zero tokens, and the
catalog cost estimate multiplied those zeros into $0.
Kimi is the visible case: a run's kimi-k3 stages report 0 tokens and no
dollars, while an openrouter stage in the same run bills normally because
OpenRouter volunteers usage (and an in-band cost) without being asked.
Send the opt-in whenever we stream. Providers that already volunteer usage
accept the field and are unaffected.

Normalize the readable reasoning providers already return into a
canonical `ReasoningOutput` and carry it through the `agent.message`
run event to storage, SSE, and JSONL.
The shape is derived from the final response's canonical message
content rather than stored a second time, so there is no duplicate
source of truth and retried or replaced streaming buffers never
become durable reasoning. OpenAI-compatible `reasoning_details` are
now preserved verbatim as an opaque content part; only known readable
members are normalized out of them, leaving encrypted entries for a
later provider-aware replay phase.
This phase is passive: no request parameters change, no capability
guessing, and no newly observed provider field is replayed.

Empty-text `agent.message` events were discarded, erasing the boundaries
between batches of tool calls. Eight short shell calls issued across five
model responses collapsed into one `Bash x8` group whose DNA bar spanned
the model-response gaps between them, showing a misleading six-minute
duration. Filtering could recreate the same artificial adjacency.
- Always emit an assistant turn for `agent.message`, carrying
`tool_call_count` so a text-free response renders as
"Requested N tool calls" instead of a blank row.
- Derive grouping and DNA timing from the complete turn stream, then
apply kind/search filters as a pure visibility pass over display
items. Hiding a tool can no longer inflate an adjacent Agent bar, and
hiding an Agent can no longer merge the tool groups on either side.
- Give a tool group the wall-clock envelope of its children (earliest
start to latest end) rather than the sum of their durations or the
span to the last array element. Row, details header, DNA bar, and
tooltip all read the same values.
- Advance the DNA previous-activity cursor by the maximum observed end
so out-of-order or overlapping completions cannot move it backward.
Frontend only: no event, persistence, or API schema changes.

Adds a Chat tab to agent stage pages alongside Thread and Debug, styled
after the Ask Fabro sidebar: agent messages render as first-class chat
bubbles (the narration between tool batches is the content that matters),
the stage prompt is a collapsed user-side card, and each run of
consecutive tool calls collapses to a wrench-icon count chip. While the
stage is running, in-flight tool calls (agent.tool.started without a
completed event) show as a live spinner line with the tool name and input
preview — data the Thread view drops today.
Thread remains the default tab; Chat becomes the default only after
production testing.
Also fixes the demo dataset: detect-drift carries the agent-flavored
stage events (prompt, agent messages, tool calls) but was labeled a
command stage, so its Thread/Chat views were unreachable in demo mode.

Guard EventScan seeks against sequences past MAX_EVENT_SEQ: a
seven-digit start prefix sorts below six-digit event keys, so an
unvalidated since_seq like 5000000 returned an incorrect slice of
history instead of an empty page. An end bound past MAX_EVENT_SEQ now
delegates to the unbounded scan, which is equivalent because no stored
sequence exceeds it.
Clamp the descending exclusive end to just past the newest stored
event, so an oversized before_seq cursor pages from the newest event
instead of probing empty key space and returning nothing.
Split RunEventListParams out of EventListParams so before_seq and
order are only accepted by /runs/{id}/events; the session, stage,
pair transcript, and demo endpoints go back to ignoring them instead
of accepting order=desc while returning ascending results.

Resolves conflicts with the shared-checkout parallel rewrite (#607) and the
cached-run/billing dedup (de60eb900):
- handler/parallel.rs: rebuilt on main's shared-checkout version. Branch
ordinals are still reserved inside the branch task right before
ParallelBranchStarted (with graph_visit/resumed_from_stage_id), and the
reserved StageScope is shared with post-await error paths via a OnceLock
slot instead of main's dispatch-time visit=1 scope, so completion events
are never emitted under a guessed ordinal.
- billing.rs: keep this branch's run_stage_from_projection (RunStage grew
graph_visit/resumed_from_stage_id and a typed id), adopt main's
state.cached_run() and drop the removed run_stage_from_stage_id import.
- run_projection.rs: adopt main's typed parallel_results
(Option<Vec<ParallelBranchResult>>).
- run_event/misc.rs: union of both sides' imports.

On a projection-cache miss, descending pagination recovered the latest
sequence by scanning the run's entire event prefix, making a cold-cache
order=desc request O(total_events). Binary-search the zero-padded
sequence key space with single-entry probes instead, bounding recovery
to O(log MAX_EVENT_SEQ) reads. The probe predicate (smallest stored
sequence at or above a bound) stays monotone across gaps left by
failed appends.

Resolved conflicts against main's shared-projection-cache rework:
- projection_cache.rs: kept main's projection_snapshot and dropped this
branch's last_seq accessor, which it subsumes; latest_event_seq now
reads the sequence from projection_snapshot.
- run_store.rs: kept main's EventScan cursor and added a seek_before
constructor so the backward-pagination range scan bounds its end key
through the same abstraction.

Event keys zero-pad seq to six digits, so an exclusive end bound past
MAX_EVENT_SEQ formatted as a seven-digit prefix that sorts before real
event keys, producing an inverted scan range. This made the newest page
come back empty once a run reached MAX_EVENT_SEQ, and let a client
supplied before_seq beyond MAX_EVENT_SEQ garble the range. Clamp the
bound and treat anything past MAX_EVENT_SEQ as unbounded; no stored
sequence exceeds it, so the results are equivalent.

- The catalog comment showed `fabro provider login fireworks`, but
`--provider` is a required flag: `fabro provider login --provider fireworks`.
- The remote-server `fabro model test` example omitted `--provider fireworks`,
which could resolve the slug against a different provider.

Resolved conflict in run_store.rs tests: kept both the new
list_events_before_with_limit tests from this branch and the
append_event_rejects_sequences_beyond_key_order_limit test from main.

- Add AppState::cached_run with the standard 500/404 mapping and use it
everywhere handlers read the shared run-projection cache. This also
normalizes two inconsistencies: graph-source cache errors now map to
500 (was 502), and a missing projection in PR create/unlink now maps
to the canonical 404 (was a bespoke 500).
- Extract an EventScan cursor shared by the four run-event scan loops,
delegate list_events_from to the paginated variant, and stop the
stage-event scan once its page is full instead of walking the rest of
the log.
- Hold Arc<RunProjection> in the local projection cache so opening a run
no longer deep-copies the projection (copy-on-write via Arc::make_mut),
and drop the now-unreachable shared-cache branch in last_event_seq.
- Trim hot-path clones: run_files serves the projection Arc directly,
run-state serializes by reference, artifacts only checks existence, and
the command-log handler opens a reader only for the CAS-blob branch.

Resolves conflicts with main's typed reasoning_effort field (#609) and
the usage-buckets test (#616). The handler's manual string parse is
superseded by serde-level validation of the typed enum, so it is
removed along with its test; the client-side unsupported-effort
validation and 400 error mapping from this branch are kept.

Copilot review flagged that dropping #[serde(default)] makes newer
clients hard-fail against servers that predate the controls field.
The late-added Model fields (default, small_default, configured) set
the precedent: required in the OpenAPI spec, defaulted on
deserialization. An empty controls list already means "unsupported",
so the degraded value is semantically correct.

Add the missing with_replacement for ModelControls so progenitor reuses
fabro_model::ModelControls instead of generating a dead parallel DTO,
re-export it from fabro_api::types, and assert type identity in the
round-trip test.
Drop #[serde(default)] from Model.controls and
ModelControls.reasoning_effort: the OpenAPI spec marks both required,
matching the strict deserialization of the sibling features/costs
fields. Update CLI stub payloads to include the now-required field.
