v0.46.0

Added

• pipeline polish steps (#244): cut_idle (finds frozen, silent stretches and cuts them in the same pass, re-timing chapters, keystroke badges, clicks, and subtitles after it), audio (two-pass normalize and measured denoise, applied to the audio as it reaches the step), burn_subtitles (an .srt/.ass re-timed onto the edited timeline, or transcribe: true), and zoom with follow: "clicks" planned from the event log.
• pipeline recipes (#244): recipe: "pr_demo" (cut idle, click zoom, GIF under 10 MB), "tutorial" (plus denoise/normalize and captions, 1080p mp4) and "social_reel" (9:16 with big captions). A recipe expands to ordinary steps that dryRun shows; your own steps replace its step of the same op, and steps the input can't support are left out with a note.
• index_recording and search_recording (#245): a searchable text timeline per recording, so an agent can find "when did the error dialog appear?" as text instead of sampling frames. index_recording cuts the video at scene changes (no stretch over 10 s goes unread), OCRs one keyframe per segment, and attaches input events, markers, and transcript cues, writing <video>.index.json (or under SCREENCAST_HOME/edits/indexes when that folder is outside the allowed output dirs); a re-run on an unchanged file reuses the OCR. search_recording returns timecoded hits, tolerant of OCR misreads or with regex: true, with secrets masked in snippets and thumbnails only when asked. The index keeps the raw screen text, so treat it like the video.
• step_guide (#172): turn a recording and its event log into a step-by-step how-to. Each click, shortcut, typing burst, and scroll becomes a numbered step with the frame just before it, the click ringed, and a caption from OCR of the text under the click ("Click Save"); markers become section headings. Writes guide.md with images and/or one self-contained guide.html. Secrets are boxed out of screenshots and masked in captions; typed text is never logged, so it never appears. A new document-steps prompt drives it.
• cut_by_transcript (#173): edit a narrated recording by its transcript. Quote the lines to drop (or cue numbers) and/or pass fillers: true to remove um/uh/erm; the cuts run in one pass that keeps audio and video in sync, and a re-timed .srt is written beside the video. dryRun returns the edited text first. Timing is as fine as the transcript; a quote inside a sentence cue is estimated and flagged exact: false.
• transcribe words: true: one word per cue with whisper's word timestamps, for word-accurate transcript edits (#173).

Changed

• cut_idle cuts audio in 256-sample chunks instead of whole AAC frames, so long edits keep audio within a few milliseconds of the video (#244).
• The event-log step builder behind bug_report is a shared helper, also used by step_guide; bug_report output is unchanged (#172).
• The tools/list size budget test is raised to 92 KB for the five new tools and the recipes (about 91 KB by default).
