Use the discover walker for MCP autoindex file-limit checks instead of shelling out to git ls-files, so non-git roots and ignored files follow the same filters as indexing.
Add typed effective config helpers so env-backed registry settings such as CBM_AUTO_INDEX_LIMIT and CBM_REINDEX_ON_STARTUP are honored consistently by MCP startup logic.
Repair the CBM_ONLY_SUITE discover allowlist and add regressions for bounded non-git discovery counts and env-over-db config priority.
