doors: adopt SyncTERM APC blob media (audio + video), no cache files

SyncTERM's blob APC verbs (Deuce, ef5b7f98a3) carry base64 media inline and
decode straight to a slot/screen with no cache file, gated on CTerm version
>= 1.329. This teaches termgfx and all five doors to use them when the client
is new enough, falling back to the existing cache path otherwise.

Detection (termgfx/caps.{c,h}):
- termgfx_caps_cterm_version() reads the version from the DA1 reply
  ("ESC[=67;84;101;114;109;MAJ;MIN;...c", 67.. spells "Cterm"): MAJ*1000+MIN.
- Named thresholds TERMGFX_CTERM_VER_{PPM=1002,BLOB=1329} replace scattered
  magic numbers (syncdoom's inline copy now calls the shared helper).

Audio (termgfx/audio.c, audio_mgr.c):
- termgfx_audio_load_blob_file()/_load_blob() build A;LoadBlob (WAV/OGG).
- stream_chunk() ships inline when the manager's blob_ok is set, else the
  legacy Store+Load with rotating cache names. Wins where audio actually
  streams: syncconquer FMV and syncretro game audio (its OGG chunks now skip
  the cache ring). The SFX/music doors keep the upload-once cache (better for
  repeated sounds) -- blob_ok is set there only for uniformity.

Video (termgfx/apc.c):
- termgfx_apc_image() gains a blob mode: C;DrawJXLBlob/DrawPPMBlob inline vs.
  the per-frame C;S Store + Draw. Wired in the JXL/PPM-tier doors
  (syncconquer, syncduke, syncdoom). Sixel is already inline, unaffected.

Each door's DA1 handler enables the audio/video blob flags at >= 1329. The
stats overlay shows a blob token only when actually in use (JXL/PPM tier
inline, or retro's "a-blob" audio stream); moo1 has none.

#256 workaround (non-blob clients): the JXL/PPM frame cache filenames were
fixed strings, so two SyncTERM windows of one dialing-entry -- which share a
cache dir -- collided. Salt the name per session with the door's PID via
termgfx_session_salt() (xpdev GetCurrentProcessId): syncalert_<pid>.jxl etc.
Only the cache path is affected; blob clients write no file. (syncterm #256.)

Compile-verified across all five doors; the blob paths need SyncTERM >= 1.329
to live-test, and the fallback is unchanged so older clients are unaffected.
