GPS: fix AT response parsing (strip mmcli `response: '...'` wrapper),
fix capnp field names (horizontalAccuracy, hasFix), set system clock
directly from first GPS fix when time is invalid, kill system gpsd on
startup.
Logging: replace module-level log dir creation with init_log_dir()
called from manager_init(). Active session always at /data/log2/current
(real dir until time resolves, then symlink to timestamped dir). Add
LogDirInitialized param. Redirect both stdout+stderr for all processes.
Also: thorough process cleanup in launch scripts, dashcamd binary,
CLAUDE.md updates for GPS/telemetry/bench/logging docs.
