v1.5.0

Automated release: version and notes generated from pull requests merged since 1.4.15.

• FFMPEG_SKILL_RESULT_V2=1 adds a result_v2 key to every writing tool's --json success document: the uniform shape planned for 2.0 (output, probe, commands, metrics, notes, dropped, details), built in emit() from the keys tools already report (#189). Nothing moves without it.

• feat: opt-in result_v2 key previews the 2.0 success-document shape (#193)
