Stop registering the git watcher on every MCP initialize unless auto_watch is explicitly enabled (default false). Re-index only via index_repository or when auto_watch is turned on after a manual index. Also deduplicate project DBs by canonical/git identity, tier RAM budget to 25% on 16GB machines, and make install hooks opt-in via --hooks. Co-authored-by: Cursor <cursoragent@cursor.com>

Summary
auto_watchconfig (default false). The git watcher no longer registers on every MCPinitializefor already-indexed projects — this was causing background re-index storms even whenauto_indexwas false.index_repository, or whenauto_watch trueis set after a manual index.cbm_find_existing_project_namematches canonical/git identity so the same repo opened from different paths reuses one index.--hooks(PreToolUse Grep/Glob augmenter no longer installed by default).Motivation
On a 16GB Windows machine with multiple indexed projects, the MCP server reserved ~8GB RAM and pegged CPU from watcher-driven re-indexing plus hook-augment spawning on every Grep/Glob.
