docs: update AGENTS.md with complete module listing

[arnoldwender]

Summary

• Updated project structure to list all 27 modules (was 12)
• Added missing top-level directories (docs/, integrations/)
• Fixed coverage threshold: 85% → 80% (matches actual CI config)
• Added key file references for entity detection, memory layers, and palace maintenance

Why

AGENTS.md listed 12 out of 27 modules, missing important files like layers.py, dedup.py, migrate.py, repair.py, entity_detector.py, and entity_registry.py. Contributors looking for where to make changes couldn't find the right file from the docs.

Test plan

• No code changes — documentation only
• Module list verified against ls mempalace/*.py
• Directory list verified against ls -d */
• Coverage threshold verified against .github/workflows/ci.yml

Clean and necessary update — 27 modules listed vs the old 12 is a significant gap that would trip up new contributors.

The additions are all legitimate modules (layers.py, dedup.py, migrate.py, repair.py, entity_detector.py, entity_registry.py) that do real work and deserve documentation. The coverage threshold correction (85% → 80%) matching actual CI config is a good catch too.

LGTM.

LGTM — the expanded module listing is much more useful for contributors trying to locate the right file. The coverage threshold fix (85% → 80%) is correct; CI was already at 80% so this removes a confusing discrepancy.

Two small observations (non-blocking):

• The description on still says "ChromaDB access" — that will become stale if #574/575 land and the backend abstraction moves there. Worth updating proactively to "backend-agnostic storage access" or similar.
• could note it's primarily for rollback scenarios (chromadb automatically handles upgrades from 0.4.1+), which #581 makes more salient.

Rebased onto develop — test file restored, version.py synced to 3.2.0. Triggering fresh CI.

Closing to reopen as a fresh PR so CI can run (PR was stuck at 'action_required' from first submission — upstream approval gate never cleared).
