release: v0.29.0 — the task-layer round-out + hardening release (#537)

Cut v0.29.0. Highlights (full detail in CHANGELOG [0.29.0]):
- task_self (#526) + task_detach (#530): tasks learn their own id and
  fire-and-forget tasks reap their handle slot — the 255-task cap now
  bounds concurrent tasks, not lifetime spawns; task_kill no longer
  poisons the ready queue.
- Three deep runtime fixes surfaced by the liferaft #523 migration:
  the JIT is task-gated at every entry point (#533), same-instant
  sleeper wakes are allocation-history-independent (#535), and
  dict_remove no longer inflates its hash table exponentially.
- lib/supervise (#409), lib/sync + must_not_yield (#488), catchable
  deadlock (#509), args on the tape (#471), eigs.json lint allow-list
  (#455), W018 (#469), silent-tolerance audit cleared (#490-#512).

VERSION, CHANGELOG section, CLAUDE.md latest-release line, and
docs/llms.txt stamp move together (doc_drift rule 2 resolves when the
dispatch creates the v0.29.0 tag).
