fix(build): ship the ffmpeg CLI in the macOS .app so transcription works without a system ffmpeg - #618

…rks without a system ffmpeg The mac pack vendored the libav dylibs next to compositor_view.node but never staged the ffmpeg binary, so resolveFfmpeg() found no candidate in the installed app and native STT audio extraction threw FfmpegUnavailableError every time — surfaced to the user only as 'Failed to fetch' (#616). - build-macos-compositor-addon.mjs: stage the SDK's ffmpeg beside the vendored dylibs, rewriting its install names to @rpath/@loader_path (verified locally: the staged binary runs and decodes standalone). Extra libs the CLI links but the addon does not (libavdevice, …) are vendored with the same treatment. - before-pack.cjs: require the ffmpeg binary in the mac payload, so a build that would ship without it fails at pack time instead of in the field. - fetch-ffmpeg-macos.mjs: reuse the vendored tree only when it was built for the pinned deployment target; a stale tree is rebuilt instead of surviving until before-pack's floor guard refuses it.

In `@scripts/build-macos-compositor-addon.mjs`:
- Line 294: Update the path filter in stageFfmpegBinary to include
`@executable_path` dylib references alongside absolute paths, and apply the same
handling to both the to path and copied dylib paths so staged libraries remain
within the darwin-architecture directory.
In `@scripts/fetch-ffmpeg-macos.mjs`:
- Around line 179-180: Update the version comparison in the reuse guard around
toNum so equivalent two- and three-component macOS versions normalize
identically before comparison. Pad parsed version components to the same length
or otherwise use fixed-width components, preserving the existing minos <=
MACOS_DEPLOYMENT_TARGET compatibility check.
