fix(repo): always include the repo root in listWorktrees

[bryantsai]

Fixes #127.

Problem

For a main worktree whose git dir lives outside the working tree (.git file → external dir, e.g. git init --separate-git-dir), git worktree list --porcelain reports the git dir path instead of the working tree. listWorktrees() therefore returns only that path, tier-1 association never matches a session cwd, and every transcript for the repo is left at tier: null.

Change

• src/repo.js: seed paths with realpathOrSelf(root) so the working tree is always a candidate; the existing Set dedups the common case where git already reports it. The if (!paths.length) fallback becomes redundant and is removed.
• test/repo.test.js: regression test that builds a repo with --separate-git-dir, asserts the root is in listWorktrees(), and that associate() hits tier 1. Fails on main, passes with the fix.

npm test: 662 pass, 0 fail.

Speaking as Kun's firstmate.

Diff reviewed on 8e3cbb31ff874aade8dbfd5e9d3fdeee44e911ba. Fork PR from @bryantsai. After review I approved first-time fork CI, Guard generated files, and the open-time Require no-mistakes run. CI (ubuntu + macos) and Guard are green on this HEAD. Greptile 5/5 noted but not a gate (repo does not use Greptile). Not a security risk. No workflow-file changes. Local test/repo.test.js pass including the new --separate-git-dir regression. Fixes #127 closing link is intact.

Contract-class: restore. Unconfigured scan already promises tier-1 association when cwd is the live repo root. Main's listWorktrees already falls back to realpathOrSelf(root) when porcelain returns nothing; with --separate-git-dir, porcelain returns the git dir path instead, so that fallback never fires and every session lands tier: null. Seeding paths with realpathOrSelf(root) (Set-deduped when git already reports it) restores the promised working-tree candidate. Not a new always-on default path — same association contract, correct for the external-git-dir layout.

VISION per-rule

• Evidence is the only currency: aligns (keeps real session quotes in the corpus instead of silently dropping them).
• The human owns the weights: aligns (no write path, review gate, or default-review change).
• Nothing the model says is taken on faith: aligns (no staging / measurement / token-arithmetic change).
• The budget is the constraint: aligns (association only; no always-loaded growth).
• It reads what you already have and owns nothing: aligns (local harness store + local git; accuracy wins over a quieter miss that looks like no history).
• Failure is loud and named: aligns (fixes root separate-git-dir shape; regression test fails if root is omitted from listWorktrees).
• Scope: aligns (listWorktrees / tier-1 association only).

This is waiting on you (the author), not on a captain decision.

Blocker: PR body has no no-mistakes ## Pipeline attestation. Open-time Require no-mistakes failed: "This PR was not raised through no-mistakes." Contributions must go through git push no-mistakes so the body gets a head-SHA-bound attestation (review / test / document completed). See CONTRIBUTING.md.

Please run a real git push no-mistakes that rewrites this PR body with a head-bound attestation for the resulting HEAD. When that edited-body Require no-mistakes check is green on the attested HEAD, this is otherwise auto-merge-ready as restore (CI+Guard already green; review+merge next pass).

I will not open a competing PR.

Speaking as Kun's firstmate: closing this as stale. It has been waiting on a contributor update for 14+ days with no author push or comment (last author activity 2026-09-15; blocker was no-mistakes body attestation). Reopen if you want to pick it back up — #127 remains ready-for-pr.
