Anto01 8ea53f4003 feat: fold project-scoped memories into context pack ...

The retrieval-quality review on 2026-04-11 found that active
project/knowledge/episodic memories never reached the pack: only
Trusted Project State and identity/preference memories were being
assembled. Reinforcement bumped confidence on memories that had
no retrieval outlet, so the reflection loop was half-open.

This change adds a third memory tier between identity/preference
and retrieved chunks:

- PROJECT_MEMORY_BUDGET_RATIO = 0.15
- Memory types: project, knowledge, episodic
- Only populated when a canonical project is in scope — without
  a project hint, project memories stay out (cross-project bleed
  would rot the signal)
- Rendered under a dedicated "--- Project Memories ---" header
  so the LLM can distinguish it from the identity/preference band
- Trim order in _trim_context_to_budget: retrieval → project
  memories → identity/preference → project state (most recently
  added tier drops first when budget is tight)

get_memories_for_context gains header/footer kwargs so the two
memory blocks can be distinguished in a single pack without a
second helper.
