feat(statusline): surface GSD milestone/phase/status when no active todo (#1990)

When no in_progress todo is active, fill the middle slot of
gsd-statusline.js with GSD state read from .planning/STATE.md.

Format: <milestone> · <status> · <phase name> (N/total)

- Add readGsdState() — walks up from workspace dir looking for
  .planning/STATE.md (bounded at 10 levels / home dir)
- Add parseStateMd() — reads YAML frontmatter (status, milestone,
  milestone_name) and Phase line from body; falls back to body Status:
  parsing for older STATE.md files without frontmatter
- Add formatGsdState() — joins available parts with ' · ', degrades
  gracefully when fields are missing
- Wrap stdin handler in runStatusline() and export helpers so unit
  tests can require the file without triggering the script behavior

Strictly additive: active todo wins the slot (unchanged); missing
STATE.md leaves the slot empty (unchanged). Only the "no active todo
AND STATE.md present" path is new.

Uses the YAML frontmatter added for #628, completing the statusline
display that issue originally proposed.

Closes #1989

### Added
- **Review model configuration** — Per-CLI model selection for /gsd-review via `review.models.<cli>` config keys. Falls back to CLI defaults when not set. (#1849)
- **Statusline now surfaces GSD milestone/phase/status** — when no `in_progress` todo is active, `gsd-statusline.js` reads `.planning/STATE.md` (walking up from the workspace dir) and fills the middle slot with `<milestone> · <status> · <phase> (N/total)`. Gracefully degrades when fields are missing; identical to previous behavior when there is no STATE.md or an active todo wins the slot. Uses the YAML frontmatter added for #628.
