docs: track tooling DX and lethe-oidc-stub follow-up (#10)

- TODO.md: mark task #5 (lethe-web-ui-aggregates) Reviewed; add task
  #10 lethe-oidc-stub (promote the in-test oidcTestServer to an
  exported testutil package, optionally a cmd/oidc-stub binary, to
  unblock real-browser smoke without standing up Authelia locally).
  New sections: Repo hygiene / Tooling DX (with the four tooling items
  now landed) and Deferred operational follow-ups (sourcecraft push +
  browser smoke for #5).
- tasks/lethe-web-ui-aggregates.md: cross-ref the deferred browser
  smoke to task #10 in Future work.

Mark task Reviewed. Conclusion captures the eight active
deviations, the four Important review findings (all
resolved in 3fbbfc8 and 1818fac), the verify checklist
(positive / negative / invariant / interface checks all
passing), and the deferred items needing user smoke
through the new SPA routes in a real browser.
