passepartout: v0.6.0 — Time Awareness

Level 2: symbolic-time-memory skill
- memory-objects-since(timestamp) — hash-table walk, objects with version >= timestamp
- memory-objects-in-range(since until) — version between two timestamps
- context-query-with-time — extended query with :since :until
- 6 tests, 100% pass

Level 3: sensor-time skill
- format-time-for-llm — TIME: section for system prompt (iso/natural format)
- session-duration — session start tracking
- sensor-time-tick — deadline scanning, cron-registered, 0 LLM tokens
- TIME_AWARENESS / TIME_FORMAT / DEADLINE_WARNING_MINUTES env vars
- 13 tests, 100% pass

Level 1: TIME injection in think() (core-reason)
- fboundp-guarded call to format-time-for-llm
- session duration included when sensor-time skill loaded
- Injected at top of system prompt in both token-economics and fallback paths
