## [0.1.0] - 2026-06-08

### Added
- Initial release: `GitLabApi` trait + `GitLab` client wrapping the `glab` CLI,
  mirroring `vcs-github`'s shape (async, `#[non_exhaustive]` DTOs, the structured
  `processkit::Error`, the `mock` feature → `MockGitLabApi`, and the
  `GitLab::with_runner` scripted-runner seam).
- The **lean merge-request lifecycle**, deserializing `glab … --output json`
  (GitLab's REST JSON): `auth_status`, `repo_view` (`Project`),
  `mr_list`/`mr_view` (`MergeRequest`), `mr_create(MrCreate)`
  → URL, `mr_merge(id, MergeStrategy)` (merges **immediately** via
  `--auto-merge=false`, overriding glab's default merge-when-pipeline-succeeds;
  `--squash`/`--rebase`/default merge), `mr_ready`, `mr_close`, and `mr_checks`
  → `CiStatus` (the MR's bucketed `head_pipeline.status`).
- `auth_status` documents the glab exit-code caveat ([gitlab-org/cli#911]): a
  `true` is best-effort (glab can exit 0 while unauthenticated); `false`/timeout
  are faithful.

[gitlab-org/cli#911]: https://gitlab.com/gitlab-org/cli/-/issues/911
- Raw escape hatches `run`/`run_raw` (+ inherent `run_args`/`run_raw_args`), and
  a `GitLab::at(dir)` → `GitLabAt` bound view mirroring every project-scoped
  method.

### Changed
- Bumped `processkit` to **0.8** — the re-exported `Error`/`ProcessResult` carry
  through 0.8 (`Error` still `#[non_exhaustive]` with `NotReady`/`Unsupported` and
  feature-gated `Cancelled`/`ResourceLimit`; `Error::Exit` Display gained a
  stderr-tail suffix; `Command` is `#[must_use]`). **Breaking** for consumers that
  match the re-exported types exhaustively, or that bump their own direct
  `processkit` separately — caret `"0.7"` does not span 0.8, so bump together.
- Internal: the `CliClient` verbs the wrapper bodies call were renamed to one
  shared vocabulary (`text`→`run`, `capture`→`output`, `unit`→`run_unit`,
  `code`→`exit_code`); no public-API or built-argv change.
- New off-by-default **`cancellation`** feature: pulls in processkit's
  `cancellation`, so `cli_client!` emits `default_cancel_on(token)` on the client —
  build a cancellable client (every command it runs dies when the token fires) and
  pass it through the facade. No new vcs-* API; `CancellationToken` is re-exported
  from `processkit`.
- `Project.visibility` is now `Option<String>` (absent in the JSON → `None`
  instead of a misleading empty string).
- `auth_status` reports `false` on **any** non-zero exit (was: errored on exits
  other than 0/1), matching its "reports the bool, must not error" contract.
- `mr_create` now takes an `MrCreate` spec
  (`MrCreate::new(title, body).source(…).target(…)`) instead of positional
  `title, body, source, target` arguments, mirroring `vcs-git`'s `GitPush`
  builder style. The built argv is unchanged.

### Fixed
- `mr_list` passes `--per-page 100` — glab's default of 30 silently truncated
  larger result sets. The cap is now explicit and documented.
