feat(lanes): per-lane database, Redis, and .env isolation (A1+A2)

Gives each lane its own slot-derived runtime (ports, detached process
lifecycle, profile-driven hooks) and its own database/Redis logical
index/.env file, so two lanes running the same repo's stack at once no
longer share state. Machine-level DB/Redis credentials live at
~/.ccam/secrets.env (mode 0600, never returned by any route); a hook's
output is redacted of that password (raw and URL-encoded forms) before
it reaches a log file or the lane_hook_output websocket broadcast.
Wired into provision/up/reset/remove; reset accepts --keep-db to skip
the drop/recreate/migrate/reseed block entirely.
