80de5ca616 refactor(static): centralize env var names
Add fabro-static::EnvVars as the shared registry for fixed environment variable names and migrate env reads, clap env bindings, and subprocess/test allowlists to use it.

Add clippy bans for raw std::env lookup APIs so future dynamic env facades must be documented explicitly.

6a87f0a071 fmt: apply nightly rustfmt after merge
Restore a clean nightly rustfmt baseline on the merged main branch so
cargo +nightly fmt --check --all passes again after bringing in
origin/main.

007cfed240 refactor: remove backwards-compat error type aliases
No production deployments exist, so there's no need for migration shims.
Remove all six backwards-compat type aliases (AgentError, SdkError,
CoreError, GraphvizError, StoreError, FabroError) and migrate ~880
callsites to use the canonical Error name directly within each crate,
or qualified imports (e.g., `use fabro_llm::Error as LlmError`) for
cross-crate references. Also fix a pre-existing absolute-path clippy
lint in fabro-server error.rs.

6ca2833e77 refactor(billing): unify the LLM billing domain
Replace the overlapping usage and cost model with canonical billing
primitives centered on ModelRef, ModelHandle, TokenCounts, and
BilledModelUsage. This also renames the public API and web surface from
usage to billing, removes compatibility aliases, and normalizes provider
usage adapters onto the shared billing vocabulary.

5b7eabee8f Add twin test mode for OpenAI E2E tests
Integrate twin-openai (fake OpenAI server) into the workspace and wire
it into the e2e_test macro so OpenAI tests can run without real API
credentials. The twin server starts in-process via OnceLock on first use
and provides per-test isolation through bearer-token namespacing.

Changes:
- Add Twin as default TestMode, replacing Off (gating now via #[ignore])
- Extend #[e2e_test] macro with `twin` requirement for twin-only,
  live-only, and dual-mode (twin + live) test gating
- Add e2e_openai!() macro returning (base_url, api_key)
- Convert openai_complete and openai_gpt_5_3_codex_complete to dual-mode
- Add new openai_server_error twin-only test with scripted 500 error
- Standardize axum 0.8 as workspace dependency across all crates
- Relax twin-openai ResponsesRequest to accept unknown fields via flatten

cd7f0b1415 Support Anthropic fast mode (speed: fast) (#127)
This PR adds support for Anthropic's fast mode beta feature (`speed:
fast`), which enables up to 2.5x faster output for Claude Opus 4.6 at a
6x pricing premium. The implementation follows the same patterns
established by `reasoning_effort`, threading a new `speed:
Option<String>` field through the request/response pipeline from graph
stylesheet properties down through agent configuration, session
management, and the Anthropic provider adapter.

On the provider side, when `speed: "fast"` is set, the `ApiRequest`
struct now includes the `speed` field in the serialized JSON body, and
the `build_beta_header` function injects the required `anthropic-beta:
fast-mode-2026-02-01` header alongside any existing beta headers (cache,
interleaved thinking, etc.) without duplication. The response's
`usage.speed` field is parsed and propagated back through both streaming
and non-streaming paths into `StageUsage` and `Usage` types for
tracking.

Cost accounting applies a 6x multiplier in `compute_stage_cost` when
`speed == "fast"`, reflecting Anthropic's actual pricing differential.
The feature is configurable via stylesheet (`* { speed: fast; }`), which
gets wired through `SessionConfig` and prompt-mode `Request`
construction in the backend layer. New tests cover the API request
serialization, beta header injection, combined cache+fast-mode headers,
and the cost multiplier, while all existing test fixtures have been
updated with `speed: None` to maintain struct exhaustiveness.
