/**
 * Escape a path for ffmpeg's `subtitles=` filter argument.
 *
 * Cross-platform rules (verified against RightNow-AI/openfang's clip skill
 * + ffmpeg's filter manual):
 *   - Forward slashes, never backslashes — ffmpeg's filtergraph parser
 *     treats `\` as an escape; on Windows paths come in as `C:\foo` and
 *     must become `C:/foo` first.
 *   - The drive-letter colon (`C:`) MUST be escaped as `C\:` because the
 *     filtergraph uses bare colons as arg separators.
 *   - Single quotes inside the path get backslash-escaped.
 *
 * Result for a typical Windows abs path:
 *   `C:\Users\me\subs.ass`  →  `C\:/Users/me/subs.ass`
