Garry TanandClaude Opus 4.7 de027ceb43 feat(migrations): TS registry replaces filesystem migration scan
Context: Codex flagged that bun build --compile produces a self-contained
binary, and the existing findMigrationsDir() in upgrade.ts:145 walks
skills/migrations/v*.md on disk — which fails on a compiled install
because the markdown files aren't bundled. The plan's fix is a TS
registry: migrations are code, imported directly, visible to both source
installs and compiled binaries.

- src/commands/migrations/types.ts: shared Migration, OrchestratorOpts,
  OrchestratorResult types.
- src/commands/migrations/index.ts: exports the migrations[] array,
  getMigration(version), and compareVersions() (semver comparator).
  The feature_pitch data that lived in the MD file frontmatter now
  lives here as a code constant on each Migration, so runPostUpgrade's
  post-upgrade pitch printer can consume it without a filesystem read.
- src/commands/migrations/v0_11_0.ts: stub orchestrator + pitch. The
  full phase implementation lands in Lane C-1; for now the stub throws
  a clear "not yet implemented" so apply-migrations --list (Lane A-4)
  can still enumerate the migration.

test/migrations-registry.test.ts: 9 tests covering ascending-semver
ordering, feature_pitch shape invariants, getMigration lookup, and
compareVersions edge cases (equal / newer / older / single-digit
across major bumps).
