ci: run independent steps in parallel

[Makisuo]

Uses the new step-level `parallel:` group in Actions.

• TypeScript: `web` and `build-other` fold into `quality`. One turbo build covers every bundle the checks read, then 8 read-only checks run as a parallel group (schema, iOS OpenAPI, tokens, browser size, alchemy tsc, web bundle budget, web typecheck, knip). Two fewer jobs pay ~30s setup and hold a runner slot. Web typecheck uses `--only` so no turbo run inside the group restores dist/ under the others.
• Local checkpoint native: the three probes (83s + 21s + 37s on main) run in parallel. They already use separate TMPDIRs and ports. Expected job time ~190s to ~135s.

Watch for: probe flakiness under CPU contention, and memory pressure from tsc + knip + web typecheck sharing one runner.

📝 Walkthrough

Walkthrough

The CI workflow consolidates TypeScript production builds and quality checks in a shared shard. It also runs three native probes as parallel steps while retaining their individual settings.

Changes

CI workflow

Layer / File(s)	Summary
TypeScript quality shard .github/workflows/ci.yml	The matrix removes the web and build-other shards. The quality shard builds production bundles for web, Alchemy, browser, effect-sdk, landing, and local-ui, then runs schema, OpenAPI, token, bundle-budget, typecheck, and Knip checks in parallel. Web typechecking uses --only.
Parallel native probes .github/workflows/ci.yml	The checkpoint, checkpoint refresh/crash-recovery, and local-store migration probes run as parallel steps. Each retains its timeout, environment, temporary directory setup, and script.

Maple review

🟢 Confidence 9/10 · safe to merge
Every check the two removed shards ran survives in the merged shard, and both parallel groups ran green on this head.
_{quality 100/100 · no findings · tests not needed · risk low}

Folds the web and build-other TypeScript shards into quality and runs the eight read-only checks and the three native checkpoint probes as step-level parallel groups. The same checks and builds still run, with no shared mutable state between parallel steps.

• web and build-other matrix shards removed; their builds fold into quality
• One turbo build covers web, landing, local-ui, browser, effect-sdk and alchemy
• Eight read-only checks run in a parallel: group, web typecheck with --only
• The three local checkpoint probes run in parallel, each with its own TMPDIR and port

What was checked

• No check was lost: all eight group steps and both former web steps are present at ci.yml:260-311
• The three probes keep distinct ports (45231, 45233, 45241) and TMPDIRs, so nothing collides
• Removing shard names is safe: branch protection requires only CI passed (ci.yml:846-852)
