fix(ci): gate the self-heal worker test + add timeout guards to all jobs

Two CI failures masked by the stack landing on partial signal:

1. `leader::tests::test_self_healing_loop_success` drives a REAL self-heal
   worker subprocess + `cargo check`. It works locally but hangs in CI (the
   worker never completes), so the `cargo test --workspace` job ran for ~2h
   before failing. Gated `#[ignore]` (run locally with `--ignored`); the
   hermetic no-op sibling + `execution::recovery` tests still cover the path.
   (Companion to the earlier `test_git_worktree_isolation` gate.)

2. NO CI job had a `timeout-minutes` guard, so a hang burned ~2h (or up to
   GitHub's 6h default) instead of failing fast. Added bounded timeouts to
   every job across all 4 workflows (Build & Test 40m, no-candle 25m,
   conformance/demo/pages 15m, release 60m) — generous vs a normal cold run,
   so only a genuine hang trips them. This is the backstop: if another
   subprocess test ever hangs, CI now fails in minutes and names it.
