project-ux: archive/rename/Open-in-Gitea sidebar context menu, archived projects landing, create-project bootstrap with Gitea remote

Server:
- projects.status + projects.gitea_remote (additive) with CHECK ('open','archived')
- GET /api/projects?status=archived; PATCH /api/projects/:id (rename);
  POST /api/projects/:id/archive | unarchive; POST /api/projects/create
- POST /api/projects ON CONFLICT (path) DO UPDATE SET status='open': re-add
  of archived path restores existing row (preserves id + FKs); already-open
  path returns 409. Detected-repos picker now excludes only status='open'.
- New gitea.ts (createGiteaRepo + GiteaRepoExistsError) and
  project_bootstrap.ts (sanitize name, mkdir under PROJECT_ROOT_WHITELIST,
  git init -b main + first commit with -c user.name/email per-command, optional
  Gitea repo create + remote add + push; all via execFile, no shell).
- 3 new user-stream frames: project_archived, project_unarchived, project_updated.
- sidebar.ts now selects path + gitea_remote and filters status='open'.
- Gitea env added to config.ts (GITEA_BASE_URL, GITEA_USER, GITEA_TOKEN,
  GITEA_SSH_HOST).
- docker-compose.yml /opt mount flipped to rw so create-project can mkdir.
- auto_name.ts gate relaxed from `!== 1` to `< 1` (fires on every turn while
  chat name is empty, not only the first).

Web:
- ProjectSidebar: project rows use proper Radix ContextMenu; items Rename /
  Archive / Open in Gitea. Inline rename, archive confirm dialog.
  Removed obsolete handleRemove + DropdownMenu hack.
- Home: Add-existing + Create-new buttons; collapsible Archived Projects
  section with Restore.
- New CreateProjectModal: name + live folder preview, commit msg, Private/
  Public radio, create-Gitea-remote checkbox, toast on success/warnings.
- New projectUrls.ts giteaUrlFor() — uses gitea_remote when present,
  falls back to convention URL.
- 3 new event types in sessionEvents.ts with idempotent useSidebar handlers.
- SidebarProject extended with path + gitea_remote so Open-in-Gitea can
  resolve without a separate fetch.
