docs: T1.4 cache-first prompt discipline plan 39db0b661b

Inventory of current prompt/cache/session code across Colibri:
- cost.rs: CostMode (fast/smart/max), thresholds, escalation (present)
- session.rs: 3-region prompt assembly, compaction (present)
- colibri-deepseek: STABLE_SYSTEM_PREFIX, cache probe (present)
- config.rs: DaemonConfig with cost fields (present)

Plan adds 6 integration items across 3 PRs:
1. PromptAssembly + CacheMetrics structs
2. Cost-aware trimming + auto-escalation
3. Scheduler injection + cache warming

No changes to parked branches (colibri-skills, zot harness).

feat: add PromptAssembly + CacheMetrics structs (T1.4 PR 1) 7c1a9d886a

Structural only — no behavior change. Introduces:

- PromptAssembly: named 3-region wrapper around build_prompt_messages()
  with to_messages(), immutable_prefix, appendable_log, volatile_scratch,
  total_bytes, estimated_tokens.

- CacheMetrics: per-session cache-hit tracking with hit_rate() and
  record().

- Session::build_prompt_assembly() wraps existing build_prompt_messages()
  with no logic change.

- 5 golden tests: assembly structure, empty volatile, hit rate
  calculations, record accumulation.

- Linked T1.4-PROMPT-DISCIPLINE-PLAN.md from COLIBRI-CUTOVER-PLAN.md.

No trimming, no escalation, no scheduler changes — PR 2 and 3 follow.

Parked branches (colibri-skills, zot harness) untouched.

Build: pass | Tests: 41/41 green (+5 new) | Clippy: clean | Fmt: clean
