perf(deploy): skip bun install + bun build when unchanged + faster healthz poll
perf(deploy): skip bun install + bun build when unchanged + faster healthz poll Three skip-on-failure optimisations to the self-deploy script. Each falls back to current behaviour if the check produces no answer, so nothing is silently bypassed. 1. SKIP BUN INSTALL when bun.lockb (or bun.lock) hash matches the last successful install. Stores the hash in .next/bun-install.stamp. Saves ~2-5s on the 90%+ of deploys that don't touch dependencies. First-time install + any dep change run normally. 2. SKIP BUN BUILD --compile when no src/*.ts(x) file changed since the last successful compile. Same .next/build-src.stamp pattern. Saves ~5-15s on docs-only / ROADMAP-only / config-only commits. If the compiled binary is missing, builds anyway. 3. FASTER HEALTHZ POLL: 10× 500ms then 10× 2s. Most deploys are green within ~1s of systemctl restart returning, so the old fixed 2s loop wasted 1-3s. Same ~30s outer ceiling. Expected combined effect on the common warm-deploy case: 25s → 12-18s. Cold (lockfile changed): unchanged. Bigger wins (collapse 11+ SSH sessions in GHA, pre-build in CI, socket activation for zero downtime) are tracked in ROADMAP for a separate pass.
