Add client-side DOT syntax highlighting for docs 
Mintlify's custom TextMate grammar support doesn't work in production
builds (see mintlify/discussions#3401). Work around this with a lightweight
JS script that applies regex-based highlighting to code blocks containing
digraph definitions, matching Shiki's inline style format.

Add Codex endpoint support for OpenAI OAuth flow 
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`.

Move sandbox lifecycle into the engine (#22) 
This PR moves sandbox lifecycle management (initialization, setup
commands, devcontainer phases, and cleanup) from the CLI's `run_command`
god function into the workflow engine. Two new engine methods are
introduced: `run_with_lifecycle()` orchestrates sandbox init, fires the
`SandboxReady` hook (now blocking by default), emits a new
`SandboxInitialized` event, handles remote git setup, runs setup
commands and devcontainer lifecycle phases, then delegates to the
existing `run_internal()` graph execution. `cleanup_sandbox()` fires the
`SandboxCleanup` hook and optionally tears down the sandbox. Both
`SandboxReady` and `SandboxCleanup` hook events were previously defined
but never fired — they now fire naturally within the engine alongside
all other hooks.

The CLI is simplified significantly: sandbox record persistence and
progress UI updates are handled via an event listener for
`SandboxInitialized` rather than inline code. The `run_from_branch`
resume path also benefits, gaining hook support and proper cleanup for
free. A new `LifecycleConfig` struct captures setup commands, timeouts,
and devcontainer phases, keeping the engine's API clean. The existing
`run()` method is unchanged, so API server and integration tests
continue working with pre-initialized sandboxes.

The `setup_remote_git` helper is moved from `cli/run.rs` into
`engine.rs` since it only depends on sandbox exec. Config is now passed
by mutable reference to `run_with_lifecycle` so the engine can fill in
remote git fields (base SHA, run branch) that downstream code needs.
Comprehensive tests verify event emission ordering, setup command
execution/failure, and cleanup behavior.

Wire up missing hook invocations (#19) 
This PR wires up three `HookEvent` variants—`StageRetrying`,
`ParallelStart`, and `ParallelComplete`—that were defined in the enum
and documented but never actually invoked by the engine. `StageRetrying`
hooks now fire at both retry sites in `execute_with_retry` (error-retry
and explicit-Retry-status paths) immediately before the backoff sleep.
`ParallelStart` and `ParallelComplete` hooks fire in the parallel
handler after their corresponding event emissions, using a new
`EngineServices::run_hooks()` convenience method since the handler
doesn't have direct access to the engine's hook method.

The two remaining unwired events, `SandboxReady` and `SandboxCleanup`,
are marked as reserved with doc comments on the enum variants and
annotated in the docs table, since wiring them requires sandbox
lifecycle changes outside the engine's scope. A small
`HookContext::set_node()` helper is introduced to reduce repeated field
assignment across all hook call sites, and existing
`StageStart`/`StageComplete` hook calls are refactored to use it.

Update roadmap and standardize on Graphviz terminology 
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.

Terminology: replace all standalone "DOT" references with "Graphviz" or
"Graphviz DOT" across docs, marketing, README, AGENTS.md, and OpenAPI
spec. Changelogs left unchanged as historical records.

Add auto-merge support for pull requests via GitHub GraphQL API 
When `auto_merge = true` is set in `[pull_request]` config, Fabro enables
GitHub's auto-merge on created PRs using the `enablePullRequestAutoMerge`
GraphQL mutation. Auto-merge implies `draft = false` since GitHub doesn't
allow auto-merge on draft PRs. A `merge_strategy` field (squash/merge/rebase,
default squash) controls the merge method. Failures to enable auto-merge
(e.g. repo doesn't have the setting enabled) warn but don't fail the run.

Add --direction flag to fabro graph (#15) 
This PR adds a `--direction` (`-d`) flag to the `fabro graph` CLI
command, bringing it to parity with the web UI's LR/TB toggle buttons.
Users can now pass `--direction lr` or `--direction tb` to override the
`rankdir` declared in the DOT source before it's handed off to the `dot`
renderer.

The implementation introduces a `GraphDirection` enum (with `ValueEnum`
and `Display` derives for clap integration), an optional `--direction`
field on `GraphArgs`, and an `apply_direction` helper that uses a
lazy-compiled regex to rewrite `rankdir=…` in the DOT source—mirroring
the same approach used by the web UI. The CLI docs are updated with the
new flag, and two unit tests verify that the rewrite works correctly and
that omitting the flag leaves the source unchanged.

Add cargo-fmt post_tool_use hook and improve matcher docs 
Add a blocking cargo-fmt hook to fabro.toml that auto-formats Rust
files after write_file, edit_file, or apply_patch tool calls. Improve
the hooks documentation with a detailed matcher field reference table,
tool name catalog, cross-field matching caveat, and additional examples.

Random Edge Selection (#12) 
This PR introduces a `selection="random"` node attribute that enables
weighted-random tiebreaking when choosing among candidate outgoing
edges. The existing deterministic behavior (highest weight, then lexical
node ID) remains the default. The cascade priority—conditions →
preferred label → suggested next → unconditional → fallback—is
unchanged; randomness only replaces the final pick-one-from-candidates
step within each tier. A new `weighted_random` function handles the
sampling, treating edges with weight ≤ 0 as weight 1, while a
`pick_edge` dispatcher routes to either the random or deterministic
strategy based on the node's `selection()` accessor.

A validation rule (`RandomSelectionNoConditionsRule`) rejects nodes that
combine `selection="random"` with conditional edges, since condition
evaluation order would conflict with random selection. A companion rule
(`SelectionValidRule`) warns on unrecognized selection values. Both are
registered as built-in lint rules with appropriate error/warning
severities and actionable fix suggestions.

Documentation is updated in the transitions guide with a new "Random
selection" section explaining the behavior and constraints, and the DOT
language reference gains a `selection` row in the node attributes table.
All changes were developed following red/green TDD cycles with
comprehensive test coverage for the accessor, weighted random sampling,
edge selection integration, and both validation rules.

Rename [feature_flags] to [features] (#11) 
This PR renames the `[feature_flags]` configuration section to
`[features]` and the corresponding `FeatureFlags` type to `Features`
across the entire stack. The change touches the OpenAPI spec (source of
truth), Rust config/API crates, the generated TypeScript API client, the
web application, and the demo config file to ensure consistency.

On the Rust side, the `FeatureFlags` struct becomes `Features` in
`fabro-config`, and all field references (`config.feature_flags` →
`config.features`) are updated in `fabro-api` demo/test code along with
the relevant unit tests. On the TypeScript side, the generated client
reflects the OpenAPI rename (`feature-flags.ts` → `features.ts`,
`FeatureFlags` → `Features`), and manual edits in `fabro-web` update the
`AppConfig` interface, defaults constant (`FEATURES_DEFAULTS`), loader
data destructuring, and template usage throughout `config.server.ts`,
`app-shell.tsx`, and `start.tsx`.

The regeneration also picked up an unrelated new `GitHubConfiguration`
schema that was already present in the OpenAPI spec but hadn't been
generated yet, resulting in the new `git-hub-configuration.ts` file and
its addition to the server configuration type.

Inject GitHub App IAT into Sandbox as GITHUB_TOKEN (#7) 
This PR adds GitHub App Installation Access Token (IAT) injection into
sandboxes, allowing `gh` CLI and other GitHub-authenticated tools to
work seamlessly inside workflow sandboxes. Workflow authors can declare
required GitHub permissions in `workflow.toml` under a `[github]`
section (e.g., `permissions = { contents = "write", pull_requests =
"read" }`), with project-wide defaults available in `fabro.toml`.
Workflow-level config fully replaces project-level defaults, consistent
with existing `[pull_request]` behavior.

The implementation introduces a `GitHubConfig` struct wired through
`WorkflowRunConfig`, `RunDefaults`, and `ProjectConfig`, with proper
`apply_defaults` (inherit if unset) and `merge_overlay` (replace if
present) semantics. At runtime, a new `mint_github_token()` helper signs
a JWT, resolves the repo's owner/repo from the origin URL, and requests
a scoped IAT which is injected as `GITHUB_TOKEN` into the sandbox
environment. The previously private
`create_installation_access_token_with_permissions` in `fabro-github` is
made public to support this. A preflight check also mints a token during
validation to surface credential or permission issues early.

Comprehensive tests cover TOML parsing with and without `[github]`,
default inheritance, workflow-over-default precedence, and overlay merge
semantics for `RunDefaults`.

- Add `hooks` and `mcp_servers` to `RunDefaults` with merge logic
- Extend `ProjectConfig` with all run-defaults fields + `into_run_defaults()`
- Remove duplicate `McpServerEntry` from fabro-config (use run_config's)
- Move `hook_config` from ServerConfig into `run_defaults.hooks`
- Wire project config merge and hooks/mcp fallbacks in run_command()
