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.

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.

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.
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.

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.

provider profiles, events, tool hooks, error handling) and the existing
fabro-llm reference.

Remove the separate CheckpointSaved event — CheckpointCompleted now fires in
both git and non-git paths. git_commit_sha is Optional (None when git is
disabled or for start nodes). The CheckpointSaved hook event is preserved
unchanged for backward compat with user hook configs.
