morning_briefing: flat file storage at sol/briefing.md master

Change briefing storage from sol/briefing/{day}.md to sol/briefing.md (same pattern as pulse.md). The day is in the YAML frontmatter. Fixes PermissionError when cortex agent writes to a new subdirectory. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
