chore: add log-tag lint + fix biome errors + pre-push hook

- scripts/lint-log-tags.sh: static check for invalid Crockford Base32 log tags (I/L/O/U)
- fix two invalid log tags in ws-client.ts (6CJX2RLP→6CJX2R8P, T9W2KL5H→T9W2K35H)
- fix biome errors: unused import, exhaustive deps, cognitive complexity suppression
- add pre-push git hook running bun run check
- integrate lint-log-tags into bun run check pipeline
