pgov v1.0

First tagged release. pgovd is a userspace scheduler daemon for Android that turns
/proc/pressure/cpu into six CFS scheduler writes, gated by thermal and battery state.

Highlights

• pgovd reads /proc/pressure/cpu and adjusts sched_latency_ns,
  sched_min_granularity_ns, sched_wakeup_granularity_ns,
  sched_migration_cost_ns, sched_walt_init_task_load_pct, and
  sched_uclamp_util_min off a running PSI estimate, rather than
  leaving all six on one static profile.
• Adaptive Kalman filtering of the PSI signal, with a structural-break
  check for reacting immediately to a genuine workload change instead
  of smoothing through it.
• Thermal-aware throttling: a PID controller over CPU and battery
  temperature pulls responsiveness back as thermal headroom shrinks,
  with its own setpoint tightening as battery temperature nears its
  limit.
• Boot-time calibration of tunable ranges against detected core count,
  max frequency, and thermal trip points, rather than one fixed table
  for every device.
• Idle-time cache sweep under /data/data and
  /data/media/0/Android/data, gated on display-off and interruptible
  by backlight or pressure changes.
