Adds the rest of the track-2 lifecycle commands (ADR-0015 §11) and the project-switching machinery they need at runtime. Temp vs named distinction: replaced the fragile naming heuristic with an explicit `[temp]` marker in the directory pattern (`<YYYYMMDD>-[temp]-<word>-<word>-<word>`). validate_user_name already rejects brackets, so user-typed names can never collide with a temp marker. The status bar shows `[TEMP] <Display Name>` for temp projects; the prettifier strips both the date and the marker so display names are clean. save / save as: temp project's `save` opens a path-entry modal (acts as save as); named project's `save` reports "already auto-saved; use `save as`". `save as` always prompts. Relative names resolve under <data-root>/projects/; absolute paths used as-is. Copy excludes the per-process lock file; everything else (.db, yaml, csvs, history.log) is copied. new: closes current project, creates a fresh auto-named temp, switches. load: opens a picker. List sub-mode shows projects in the active data root, sorted newest-first by project.yaml mtime; arrow keys navigate, Enter loads, `b` switches to a path-entry sub-mode for projects elsewhere, Esc cancels. Empty data root jumps straight to path entry. Runtime: `Session` holds Option<Project> + Option<Database> so project switches can drop old (releasing lock + stopping worker) before opening new -- required for the "load my own current project" case. `perform_switch` handles Load / SaveAs / NewTemp uniformly. Tests: 332 passing (270 lib + 9 + 5 + 6 + 16 new + 9 + 17), 0 failing, 0 skipped. Clippy clean.
