- mnemopi provider parity 'diagnose, validate, graph' does ~6.7s of real
work under bun --parallel=8 on loaded runners; raised its per-test
timeout to 30s (default 5s flaked twice in three CI runs).
- utils LRUCache updateAgeOnGet drove a 30ms TTL with real 20ms sleeps
(10ms margin); now drives performance.now() via a mocked clock, so the
contract is asserted deterministically with no wall-clock wait.
- Implemented in-house, zero-dependency utility modules in `pi-utils` covering DOM manipulation, markdown parsing, templating, browser automation helpers, and terminal buffers.
- Migrated packages across the repository to consume the new internal utilities and `omptype` schema validators instead of external dependencies.
- Removed multiple external runtime and development dependencies including Zod, Marked, LRU cache, Turndown, and Puppeteer browser packages.
