feat(ui): forge user lookup — assignee combobox, @-mentions, repo-scoped user search

Repo-scoped assignable-user search for GitHub, GitLab, and Gitea, surfaced as
an assignee combobox in the metadata editor and @-mention autocomplete in
forge comment/reply/review surfaces.

- server: GET /api/{provider}/users/search (assignees / project members),
  query + directory/override repo resolution, 429 -> 503, connected:false
  degradation; GitLab assignee writes resolve login -> ID server-side
- wire: searchUsers (+ searchLabels/milestones/branches/tags) on the three
  API clients with tests
- facade: userSearch capability (all three), searchUsers adapters,
  mapGithubAssignee/mapGitlabMember/mapGiteaAssignee -> ForgeUser
- ui: ForgeLookupCombobox (keyboard nav, debounced 30s-TTL cache,
  connected-only caching), ForgeMentionTextarea (@ token parsing, caret
  restore), free-text fallback when lookup is unavailable; i18n in 12 locales
- extras sharing the same infrastructure: GitLab create-issue dialog and
  label/milestone/branch/tag lookups in the metadata editor

All write routes accept an optional `owner`/`repo` in the body to target a fork-network repo; otherwise the repo is resolved from `directory`. Unauthenticated -> `{ connected: false }`; `429` -> `503 { error: 'GitHub rate limited' }`; generic failures -> `500` with a generic error (raw upstream text is never leaked).
- `POST /api/github/issues/comment` — body `{ directory, number, body, owner?, repo? }` -> `{ connected, repo?, comment? }` (via `octokit.rest.issues.createComment`, mapped to `GitHubIssueComment`).
- `POST /api/github/issues/create` — body `{ directory, title, body?, labels?, owner?, repo? }` -> `{ connected, repo?, issue? }` (via `octokit.rest.issues.create`; `labels` is a full-set list of names).
- `PATCH /api/github/issues/update` — body `{ directory, number, title?, body?, state?, labels?, assignees?, milestone?, owner?, repo? }` -> `{ connected, repo?, issue? }` (via `octokit.rest.issues.update`; `labels`/`assignees` replace the full set, `milestone` is a title resolved to a milestone number — `400 { error: 'Milestone not found' }` when it matches nothing, `null` clears it). Also works for pull requests (PRs are issues), so it serves PR metadata/state changes too.
- `POST /api/github/pulls/comment` — same input/result shape as `issues/comment`; posts to the PR's issue thread via `octokit.rest.issues.createComment`. Invalidates the PR context cache.
- `POST /api/github/pulls/review-comment` — body `{ directory, number, body, inReplyToId?, path?, line?, owner?, repo? }` -> `{ connected, repo?, comment? }` (via `octokit.rest.pulls.createReviewComment`). With `inReplyToId` it is a reply; otherwise `path` + `line` are required and the PR head commit is resolved first. Invalidates the PR context cache.
