[docs] docs/module-inventory.md per-layer file counts are stale #563

What happened

docs/module-inventory.md:61-64 states per-layer file counts that no longer match the tree.

Reproduction steps

Run find mcp_server/<layer> -name '*.py' -not -path '*__pycache__*' | wc -l for each layer at commit a3b3a79d and compare with lines 61-64.

Expected behavior

The inventory never states a number that can drift silently: either the counts are removed, or a check (for example in scripts/check_craftsmanship.py, which already parses this file's layer table) fails when they diverge.

Environment

Cortex 4.21.0, commit a3b3a79

Severity

Low (cosmetic, edge case)

Evidence required to close

Counts corrected and a CI check that fails on drift, or the counts removed.
