Long-running website monitoring: new cloud/resident.py layer on top of
the automations claim/quota model (no task state-machine change).
States running/paused/ended; pause preserves the content-hash cursor
and stops polling, resume re-checks from the cursor, end is terminal
(resume after end is 409, a new watch is required). Polling is a cheap
fetch + hash comparison; only a real change creates a queued model
task. Quota exhaustion pauses (quota_exceeded) instead of ending and
keeps the cursor. Driver is the worker run_loop round boundary;
server exposes create/list/get/update/pause/resume/end with audit.
Console UI intentionally not wired this round (see verification
summary for deviations).
