…able Add top-level `timezone` config option (default: "system") supporting IANA names and UTC offset strings (ECMA-402 2024). - Introduce unified `src/utils/time.ts` module with formatForLLM, formatLocalDate, formatLocalDateTime, startOfLocalDay, nowInstantISO - Converge 4 scattered time helpers into the single module - L1 extraction / auto-recall / scene-extraction / persona-generation prompts now emit ISO 8601 with explicit UTC offset - Add timezone declaration to LLM system prompts - Local-day shard boundaries and cleaner cutoff follow configured tz - Storage instants (SQLite/TCVDB) remain UTC — no data migration needed - 38 unit tests covering IANA, offset, DST, half-hour zones, fallback

This PR builds on the direction explored in #76 by @YOMXXX — we adopted the same link-path coverage (capture/L1/L2/recall) but switched from integer
timezoneOffsetMinutesto IANA timezone names for DST correctness. Thank you for the groundwork!Scope exclusion: The
offloadmodule (src/offload/time-utils.ts) is intentionally unchanged in this PR.
