Tom Boucher 4956e5e5c6 test(3598): generator correctness, parity, and atomicity (#3656) ...

Adds tests/feat-3598-generator-correctness.test.cjs covering the
gaps the existing generator/parity test surface does not exercise:

  Suite 1 — Stale-but-timestamp-valid detection: for each of the 9
  generators that export a build*Cjs() function, asserts the fresh
  in-memory output is byte-equal to the committed .generated.cjs.
  Catches manual edits and partial-write drift that timestamp-only
  freshness checks miss.

  Suite 2 — Determinism: calls each build*Cjs() twice and asserts the
  outputs are identical. Catches time/random/iteration-order regressions.

  Suite 3 — Runtime/SDK alias parity: asserts canonical command names
  and alias sets are identical between
  get-shit-done/bin/lib/command-aliases.generated.cjs (runtime) and
  sdk/src/query/command-aliases.generated.ts (SDK). Beyond timestamp
  freshness.

  Suite 4 — No duplicate aliases in the live registry: behavioral
  equivalent of the issue's example test. The generator has no
  fixture/--source seam (it reads in-memory COMMAND_DEFINITIONS_BY_FAMILY),
  so the structural invariant is asserted on the deployed surface; a
  collision fails with both colliding canonicals named.

  Suite 5 — build-hooks.js atomicity: runs the build twice, snapshots
  hooks/dist/ each time, asserts byte-identical output. Also asserts
  no orphaned .dist-staging-* sibling directories remain and that every
  .js file shipped to dist parses (positive proof of the vm.Script
  syntax guard).

26 tests pass on macOS / Node 24.

Closes #3598
