Reduced-rate modeld path now branches on IsDaylight:
- daylight: skip 1/2 frames → 10fps (better model responsiveness when
lighting gives the net more signal)
- night: skip 4/5 frames → 4fps (unchanged, conservative for power)
IsDaylight is already in /dev/shm (memory) via gpsd.py. Gated the
IsDaylight write on change — it flips twice a day, no reason to rewrite
every 30s. GPS polling bumped from 1Hz → 2Hz.
ModelFps publishes "10" / "4" / "20" so longitudinal_planner's dt and
FCW-threshold scaling (if re-enabled) still track actual rate.

Decouples "tell modeld to go fast" from "steering actually active":
- New LatRequested memory param — controlsd writes when lat would be active
- modeld reads LatRequested (not carControl.latActive) for FPS decision,
so it switches to 20fps immediately on engage request
- controlsd delays CC.latActive becoming true by 250ms (5 frames @ 20fps)
after LatRequested goes true, giving downstream services
(longitudinalPlan, liveCalibration, etc.) time to stabilize at the new rate

- Fan controller: allow full 100% fan when offroad temp >= 75°C (startup cooling)
- ModelFps memory param: modeld publishes actual FPS (20 or 4) so downstream
consumers can adjust frame-rate-dependent logic
- Longitudinal planner: dynamically adjusts dt and v_desired_filter based on
ModelFps; FCW crash_cnt threshold scales with FPS to maintain consistent
0.15s trigger window at both 20fps and 4fps
- controlsd: suppress commIssue alerts for 2s after lateral control engages
(FPS transition from 4->20 causes transient freq check failures)
- Shutdown timer: hardcoded to 10 minutes (was 45min via FrogPilot param),
screen taps reset the countdown via ShutdownTouchReset memory param,
removed Shutdown Timer UI selector from ClearPilot menu

- modeld: full 20fps (lat active), 4fps (driving no lateral), 0fps
(standstill). Standby timestamp written in both standby and 4fps modes
to suppress transient errors on engagement transition
- tlog: all calls commented out (was causing 100Hz CPU load in controlsd
and carstate). tlog client now checks TelemetryEnabled param before
sending — zero cost when disabled
- dashcamd: wait for valid frame dimensions on startup (fix SIGSEGV),
always_run (manages own trip lifecycle)
- Fan: driving range 15-100%

- modeld: enter standby when latActive=false (not just standstill),
exception for lane changes (no_lat_lane_change). Fix Python capnp
property access (.latActive not getLatActive())
- controlsd: move model_suppress computation early, suppress radarFault,
posenetInvalid, locationdTemporaryError, paramsdTemporaryError during
model standby + 2s grace period. All cascade from modeld not publishing
- dashcamd: always_run (manages own trip lifecycle), wait for valid frame
dimensions before encoding (fix SIGSEGV on early start)
- Fan: driving range 15-100% (was 30-100%)
