* docs: add token budget enforcement analysis and fix plan
Document root cause of context window overflow (2.7M tokens sent to 1M
model): L4 chat history bypasses all compaction systems. Add fix plan
with phased approach to enforce token budget at message assembly point.

* docs: correct root cause analysis — L1 unbudgeted, not L4
Previous analysis incorrectly blamed L4 chat history as the primary
culprit. Investigation shows L4 stores only bare L5 text + compacted
responses. The real issue is systemic: no total payload enforcement,
with L1 (project context) being the largest unbudgeted layer and
PROJECT_COMPACT_THRESHOLD being blind to L1 size.
Updated fix plan to be model-agnostic (use autoCompactThreshold as
single budget, no model-specific lookup tables), added contextTurns
deprecation, and history guarantee principle.

* fix: hard cap L1 project context at 600k tokens + payload diagnostics
- Truncate project context at 2.4M chars (~600k tokens) to prevent
total payload from exceeding model context windows (temporary fix
until full token budget enforcement is implemented)
- Add per-layer token estimate logging when payload exceeds 2M chars
to help diagnose context window overflow reports
- Document Obsidian CLI dev tools in CLAUDE.md
