v1.4.4

timps v1.4.4

Fixed

• Crash (use-after-free in libimp) on a live audio-module toggle.
  Changing audio.agc, audio.ns or audio.high_pass via /control while a
  stream was running could segfault timpsd — SIGSEGV with the fault inside
  libimp.so (epc=0, return address in libimp). The /control request
  thread called IMP_AI_Enable/DisableAgc/Ns/Hpf on the live AI channel while
  the audio thread was inside IMP_AI_GetFrame — where libimp processes those
  modules — freeing state the frame path was still using.

  The toggle is now deferred: /control only flags the change; the audio
  thread re-applies it from config at a frame-free point (loop top, no frame
  held), serialized by a dedicated lock. Volume/gain/alc_gain stay direct
  (plain parameter writes, not module create/destroy). Rapid toggles coalesce
  and converge to the final configured value; no deadlock, no lost updates.

Tooling (tools/timps-qa.sh)

• Added --only <sections> to run just selected QA sections (names or
  numbers, comma-separated), e.g. --only onvif or --only 3,10. Preflight
  always runs.
• Fixed a false positive in the on-device config-integrity check: it counted
  = inside comments (e.g. # 0=err 1=warn, # 1 = 50Hz) as "glued" config
  lines. Comments are now stripped before the check; a real a=b c=d line is
  still detected.
