wire phi to the reshaped relay-eval API + three-mode check_relays
- config: monitors_url -> relays_url (points at /api/relays base)
- tool: three explicit modes
- snapshot (no args): current fleet status
- history (name=<host>): timeseries; narrow with since/until,
or fall back to recent-N via limit. renders the full series
(downsampled past 200 points) instead of truncating to 5.
- transitions (transitions=True): fleet-wide status-change log
from /api/relays/events. answers "when did X happen."
- all params use Annotated + Field(description=...) so the LLM
sees what each does.
- operational instructions updated to name the three modes.
