feat: time awareness subsystem for continuous temporal perception

[k-QRedHacker]

Three-layer implementation:

• Layer 1: Dormancy perception in system prompt (volatile_parts)
• Layer 2: Heartbeat rhythm in API messages (5-min throttled)
• Layer 3: Lifecycle anchoring on session transition

Agent can now perceive how long it slept between sessions, current wall-clock time, and interval between turns. Does not break prompt caching. No extra LLM credits wasted.

This was a duplicate — the clean, focused version is #61837. The original bundle included 47 unrelated files that were not part of the time awareness feature. Thanks for the review @alt-glitch.
