Replace the per-run `--run-dir` CLI flag with `--storage-dir` which sets
the base storage directory (default ~/.fabro). Runs are now created under
`<storage-dir>/runs/` automatically. This unifies the server's `data_dir`
config with the CLI by renaming `FabroConfig.data_dir` to `storage_dir`
and adding a `storage_dir()` convenience method.
Key changes:
- FabroConfig: `data_dir` → `storage_dir` (serde alias preserves compat)
- CLI: `--run-dir` → `--storage-dir` on `fabro run`
- `__detached`: now takes `--storage-dir` + `--run-id` instead of `--run-dir`
- All ~20 CLI commands derive runs base from config instead of hardcoded default
- Added parameterized `runs_base(storage_dir)` and `make_run_dir()` helpers
- Updated OpenAPI spec, docs, and all tests

Preflight validation is conceptually distinct from running a workflow —
it deserves its own top-level command rather than being a flag on `run`.
- Add `PreflightArgs` struct and `Commands::Preflight` variant
- Create `commands/preflight.rs` with dedicated `execute()` function
- Remove `--preflight` flag from `RunArgs`
- Refactor `load_workflow_source_input` to take individual params
instead of `&RunArgs`
- Refactor `resolve_cli_goal` to take `Option<&str>` / `Option<&Path>`
- Refactor `run_preflight` to take `cli_model`/`cli_provider` instead
of `&RunArgs`, make `pub(crate)`
- Update docs and skills references

Resume now follows the same subprocess pattern as run: look up run
directory by ID prefix, validate checkpoint exists, clean stale
artifacts, reset status to Submitted, spawn _run_engine --resume, and
attach. This eliminates ~1600 lines of duplicated env/sandbox setup
from resume.rs.
Key changes:
- operations::start() and operations::resume() take run_dir instead
of Persisted, loading state from disk internally
- run_engine() builds RunOptions from RunRecord on disk, so callers
no longer extract record fields manually
- StartOptions flattened (no more nested InitOptions)
- FabroError::Precondition variant for start/resume guard checks
- _run_engine accepts --resume flag to dispatch to resume path
- operations::restore removed (no longer needed)
- Resume CLI stripped to just <RUN_ID> + --detach

Introduce two new persistence types aligned to the CREATE/START lifecycle:
- RunRecord (run.json): written at CREATE with merged FabroConfig, fully
transformed Graph, and run metadata
- StartRecord (start.json): written at START with start_time, run_branch,
and base_sha
All readers (run_lookup, inspect, diff, pr, attach, detached_support,
start, run_fork, pull_request, run_rewind, resume) now read from the
new types first. Legacy manifest.json + spec.json are still written
for backward compatibility (removal in follow-up).
Also adds dry_run, auto_approve, no_retro fields to FabroConfig, derives
Default on LlmConfig and Graph, and updates docs + tests.

Preserve original error chains (reqwest, serde_json, etc.) in SdkError
via Arc<dyn Error>-backed #[source] fields on Network, RequestTimeout,
Stream, and Configuration variants. This makes production debugging of
network/TLS/DNS issues easier since error reporters can now walk the
full chain. Serde-compatible via #[serde(skip)] — message string still
carries the text for serialized forms.
Also add a `type` field to ToolCall (defaulting to "function") so
non-function tool types from providers won't be silently mishandled.

Remove ErrorPolicy enum (continue/fail_fast/ignore) and the k_of_n/quorum
join policies from the parallel handler, leaving only wait_all and
first_success. This deletes ~180 lines of conditional logic including
FailFast early termination, the ParallelEarlyTermination event, and all
related tests and documentation.

- Remove any-edge fallback from select_edge() in deterministic mode; random
mode retains it as an enhancement over the base spec
- Restrict preferred_label and suggested_next_ids matching to unconditional
edges only (already applied in prior work, tests added here)
- Rename default_max_retry → default_max_retries across codebase (code, docs,
fixtures, skills) and change default from 3 to 0
- Update transitions.mdx to document edge selection cascade accurately

New page (execution/outcomes.mdx) defines the 5 stage statuses, documents
how each handler produces them, and explains allow_partial, auto_status,
the retry loop, goal gate interaction, and outcome in edge conditions.
Existing pages updated: added missing `skipped` status to outcome key
descriptions, improved `goal_gate`/`auto_status` descriptions in the
dot-language reference, added `allow_partial` to the attributes table,
and added cross-links from failures.mdx and transitions.mdx.

This PR introduces a unified `WorktreeSandbox` type in `fabro-sandbox`
that consolidates previously duplicated git worktree management logic
spread across `parallel.rs` and `run.rs`. The new type wraps any
`Arc<dyn Sandbox>`, handles the full worktree lifecycle (branch
creation, `worktree add`, and cleanup) in its `initialize()`/`cleanup()`
methods, overrides `working_directory()` and `exec_command()` to default
to the worktree path, and delegates all other `Sandbox` methods to the
inner sandbox. A `WorktreeConfig` struct controls behavior (branch name,
base SHA, worktree path, and a `skip_branch_creation` flag for resume
flows), and a `WorktreeEventCallback` mechanism bridges lifecycle events
to the workflow event system via a new
`EventEmitter::worktree_callback()` helper.
The old private `WorktreeSandbox` struct in `parallel.rs` (which only
redirected `exec_command` working dirs with no lifecycle awareness) is
removed and replaced with the shared implementation. The
`setup_worktree()` function in `run.rs` is also removed; its logic is
absorbed directly into the `SandboxProvider::Local` branch of sandbox
construction, where `WorktreeSandbox::initialize()` is called and
`std::env::set_current_dir()` follows on success. The resume path
(`run_from_branch`) similarly replaces direct `git::replace_worktree`
calls with `WorktreeSandbox` using `skip_branch_creation: true`. The
`MockSandbox` in `test_support.rs` gains `captured_commands` and
`captured_working_dirs` vectors to support sequenced-command assertions
in the new unit tests.
The `MockSandbox` enhancement is a notable improvement for testability
beyond this specific change—having the full ordered sequence of commands
rather than just the last one makes it straightforward to assert on
multi-step git workflows. One subtle behavior worth noting is that in
`parallel.rs` the `git reset --hard` step previously present after
worktree creation is now absent from `WorktreeSandbox::initialize()`;
the plan mentioned it but the implementation deliberately omits it (the
branch is already force-set to the target SHA, so the reset was
redundant for the parallel case). Cleanup for parallel branches
continues to go through `engine::git_remove_worktree` on the parent
sandbox rather than calling `wt_sandbox.cleanup()`, since the sandbox
`Arc` is consumed by the spawned task—this is a reasonable tradeoff
noted in the plan.

Route OpenAI OAuth users through the ChatGPT Codex backend API with
required headers (ChatGPT-Account-Id, originator). The Codex endpoint
requires streaming-only requests, omits unsupported fields (temperature,
max_output_tokens, top_p), and uses a different error format. Also
persists the account ID from OAuth tokens and updates CLI docs for
`fabro ps -q`.

Roadmap: replace placeholder items with current shipped/building/planned
features. Use real dates for sorting instead of manual sortOrder. Fix
UTC timezone rendering for date display.

"Graphviz DOT" across docs, marketing, README, AGENTS.md, and OpenAPI
spec. Changelogs left unchanged as historical records.
