Automated release: version and notes generated from pull requests merged since 2.2.5.

• feat(join): --on-silent warn|fail|skip (default warn) and --silence-threshold DB (default -50 dBFS). The preflight measures every input with audio (one volumedetect pass on a real run; --dry-run measures nothing and says so) and treats a peak at or below the threshold as silent -- the trace of a TTS step that wrote a valid but empty wav, which the 2.2.0 missing/empty/unreadable checks let through. warn joins it and names it under the new silent: [{index, path, peak_db}] key and in notes; fail refuses it in the same kind: input document as the other problems (silent (peak -91.0 dBFS)); skip drops it into skipped. Inputs without an audio stream are never silent. The join's own ffmpeg command is unchanged, and render.py forwards nothing new.
• fix: audio.py no longer passes a silent --music / --replace / --effects file, or a silent
  voice under --duck, as verified. Each is peak-measured in the 2.2.4 preflight (real runs; a dry run measures nothing);
  new --on-silent warn|fail (default warn: silent: [{flag, path, peak_db}] + note; fail:
  reason silent (peak X dBFS) in the one refusal) and --silence-threshold (default -50 dBFS).
• fix: no --json document contains -Infinity / NaN any more. print_json writes
  non-finite floats as "-inf" / "inf" / null (as loudness.py already did) with
  allow_nan=False; export.py on silent audio reports loudness.lufs: "-inf",
  silent: true, and a note saying "output audio is silent" instead of recommending loudness.py.
• fix(caption): a burn whose cues are never visible is refused with kind: input instead of reporting verified: true -- every cue outside [0, duration], every cue blank, or --ass with no Dialogue lines; applies to waveform.py --srt too. The caption block reports cues_burned and cues_outside, and cues partly outside get a warning note
• fix(graphics, overlay): whitespace-only --title, --name, --text (and the other text flags) count as missing and are refused instead of burning an empty graphic
• feat(check): --content (opt-in) adds black (blackdetect share: WARN > 10%, FAIL >= 95%), frozen (freezedetect longest span: WARN > max(3 s, 30%), FAIL when the whole video is frozen) and silence (silencedetect share at -50 dB: WARN > 50%, FAIL >= 95%) rows from one decode pass. Without it the row set is unchanged. render.py's check section takes "content": true to forward it.
• fix(check): the audio row no longer PASSes "present" for a silent track: FAIL under a platform/--lufs loudness target, WARN with none (a muted screen recording is legitimate), when the track is silent (peak <= -50 dBFS) -- read off the loudness pass, or from one volumedetect pass when --no-loudness or a spec without a loudness target skips it.
• fix(caption): the "re-run without --dry-run to produce X_adjusted.srt" note appears only on dry runs
• fix(join): a segment shorter than 2 frames (audio-only: 0.05 s) and a path listed twice no longer join unremarked: new short_segments: [{index, path, duration}] and duplicates: [{path, indices}] keys (always present, [] when none) plus notes. Warnings only; the join command is unchanged.
• fix(waveform): silent input audio no longer renders a flat-line audiogram without a word. A real run peak-measures the input; --on-silent warn|fail (default warn) and --silence-threshold (default -50 dBFS) as in audio.py; new silent key (null under --dry-run) and a note.
• fix(asr): a speech engine that ran and found no speech says <engine> found no speech in <input> (kind: input, reason: "no_speech", engine) instead of faster-whisper's "no local speech-to-text engine found" or whisper.cpp / openai-whisper's "no cues found in /tmp/ffskill_asr_*/audio.srt".
• feat: catch valid-but-empty content (silent TTS, invisible captions, -Infinity JSON) (#294)
