📝 Walkthrough

Walkthrough

The project now uses Bun 1.4.0. The bun-types development dependency also uses version 1.4.0. The release-age quarantine excludes bun-types.

Changes

Bun tooling update

Layer / File(s)	Summary
Update Bun tooling and quarantine configuration package.json, bunfig.toml	Updated the Bun package manager and bun-types development dependency to 1.4.0. Added bun-types to the release-age exclusion list.

Estimated code review effort: 1 (Trivial) | ~2 minutes

Merge Risk: 🟡 Moderate · up to 5108c

The PR aligns Bun configuration but leaves bun-types on a range that can admit later 1.x type definitions, and its quarantine exception may remain active after August 25, 2026 without cleanup. Merge should wait for exact pinning and explicit expiry handling.

expiry timestamp has passed; ensure the automation runs regularly and preserves
unexpired exceptions.

In `@package.json`:
- Line 60: Pin the bun-types dependency in package.json to exactly 1.4.0 instead
of using the caret range, and regenerate bun.lock so it records the matching
exact version.
