fix(utils): add missing biome noRestrictedImports rule and correct truncate docs

- Add noRestrictedImports to biome.json under style — bans nanoid and uuid
  package imports at lint time (crypto.randomUUID/randomBytes are caught by
  the check:utils grep script which handles global property access)
- Correct truncate() TSDoc and parameter name: sliceLength makes it clear
  that total output length is sliceLength + suffix.length, matching the
  behavior all callers were already written to expect
