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.

/**
* @file Tests for lane runtime isolation: slot and port allocation, profile
* parsing and hook execution, and the boot/down lifecycle.
*
* The lifecycle tests run a REAL profile whose boot hook starts a REAL server and
* whose health hook polls it, because the properties worth proving are exactly
* the ones a mock cannot show: that a service detached by `harness_spawn` keeps
* listening after the hook exits, that runtime facts recomputed from scratch still
* find it (the "survives a dashboard restart" claim), and that `downLane` reaches
* a process it never spawned directly.
