Add venv auto-activation to audio_batch, audio_connector,
image_connector, qdrant_connector, and trellis_connector.
Scripts re-exec into .venv/bin/python when invoked outside
the venv, with a friendly error if .venv is missing.

Consolidates all connector scripts under tooling/ per project
structure conventions. Symlink at db/connectors → tooling/db/
preserves backwards compatibility (remove after Sprint 22).
Updated references in CLAUDE.md, Makefile, DEVOPS.md, all skill
files, agent files, rules, schema comments, and Sprint 21
briefings. Python scripts updated with correct SCHEMA_PATH
(now relative to WORKTREE_ROOT/db/schema.sql).
