Merge remote-tracking branch 'origin/blitz/spawn-v2' into spawn-v2/96-tui-picker

Mirrors the web project-picker redesign (#95) in the TUI (#96): step one
lists one box per repository (name, full path); picking one reveals step
two — "+ new" then that repository's worktrees newest-first, defaulting
to "+ new" except on a box that is itself a linked worktree. "+ new"
creates (cwd is the repo, create-worktree on); an existing worktree runs
in it (cwd is that worktree, create-worktree off). Neither step probes
/api/gitroot — only the free-text "Other directory…" hatch does.

Replaces the flat indented project+worktree list from #91/#64 with
projects::group_projects-backed DraftGroup boxes; the filter still
matches a repository via its own name/path or any of its worktrees.

+//!
+//! The picker itself is two steps (#96), verbatim from the rules in
+//! `web/src/spawnForm.ts`'s "working-directory picker (#95)" comment:
+//!  1. Step one is one box per repository (name, then full path). A worktree
+//!     is a box only when its main checkout is missing from the scan.
+//!  2. The filter keeps a repository when the query matches it or any of its
+//!     worktrees, so a worktree name still finds its box.
+//!  3. Picking a box reveals step two: "+ new", then that repository's
+//!     worktrees newest-first. "Other directory…" clears both steps.
+//!  4. "+ new" is the default selection — except on a box that is itself a
+//!     linked worktree, which defaults to that worktree.
+//!  5. "+ new" means create: cwd is the repository, create-worktree on.
+//!     An existing worktree means run in it: cwd is that worktree,
+//!     create-worktree OFF. The daemon never adopts (docs/WORKTREES.md), so
+//!     these are separate acts.
+//!  6. Neither step probes `/api/gitroot`; the scan already reports
+//!     repository membership. Only the free-text hatch pays for a probe.
