Fix bootstrap: deep scan, CLAUDE.md fallback, noise filtering

1. Tech stack: recursive file search (depth 3) + CLAUDE.md text fallback
   when config files are on remote server (detects nodejs, postgresql, etc.)
2. Modules: scan */src/ patterns in top-level dirs (frontend/src/, backend-pg/src/)
3. Decisions: filter out unrelated sections (Jitsi, Nextcloud, Prosody, GOIP),
   filter noise (commit hashes, shell commands, external service paths).
   Noise filtering also applied to Obsidian decisions.

Tested on vdolipoperek: 4 tech, 5 modules, 9 clean decisions, 24 Obsidian tasks.
61 tests, all passing.
