Adopt staged WORK-RECORDS generation and catch the index up.

REUSE-WP-0026 finished in bf30d5e without the generated index. The opt-in
lets the pre-commit hook rebuild WORK-RECORDS.md in the same commit as
the workplan it indexes.

+## Generated work-record index
+
+This repository opts into staged-source WORK-RECORDS.md generation through
+`.generated-work-records.json` and the isolated `.generated-work-records.mk`
+recipe. `make generated-work-records` reuses the State Hub renderer through
+the Custodian adapter; `make generated-work-records-check` verifies byte-exact
+agreement with staged Markdown. The pre-commit hook uses the isolated recipe,
+preserves unstaged index edits by refusing them, and retains the generated-only
+commit guard. It does not contact the hub, alter workplan statuses, or grant
+deployment authority. This consumes shared tooling; it does not make this
+repository the provider of the generator capability.
