Session handoff covering the clause-concept-hints feature (ADR-0058, #42) and
the working-method establishment (ADR-0059, #41; fixes #43/#44). Records the
docs direct-push carve-out: handoff/session docs and small docs amendments are
owner-direct-pushed to main, because a docs-only PR posts no ci/gate run
(paths-ignored) and stalls on the required check. Amends CLAUDE.md, ADR-0059
(Amendment 1), and its README index row.
