Claude 9403e3ca46 Fix season dates, resolution, attribution, retention policies, montage trigger
season_info.py (new):
- Computes actual equinox/solstice dates via Jean Meeus approximation
- Converts to LOCAL timezone (pytz / zoneinfo) so the calendar date reflects
  what the camera sees on the ground, including DST transitions
- Timezone defaults to America/New_York; override via $TIMEZONE env or 2nd arg
- Divides each season into 3 equal movements; handles Winter's year boundary
- Outputs IS_LAST_DAY=true on the final day of each movement

4-seasons.sh:
- Uses season_info.py for all date/season logic (no hardcoded day-of-year)
- Passes $yesterday to season_info.py so astronomical dates are correct
- Removed forced 1280x720 scale; clips stay at native camera resolution
- Auto-triggers montage-mvt.sh "$yesterday" on last day of movement so the
  correct movement (not the next day's) is compiled

montage-mvt.sh:
- Accepts optional YYYY-MM-DD argument (passed by 4-seasons.sh) so it
  resolves the correct season/movement when run the morning after last day
- Detects source resolution from first daily clip via ffprobe; attribution
  card is generated at that exact resolution — no resizing of main video
- Font sizes proportional to frame height so text looks right at any res
- License corrected to CC BY-SA 3.0 (was CC BY-NC-SA 4.0)

fullday-video.sh:
- Removed 30-minute target; video length is natural (num_images / FPS)
- Default FULLDAY_FPS=5 (configurable at top of script)
- Retains RETENTION_DAYS=10 auto-delete for full-day videos only
- Sunrise 10s uploads and montage videos are never auto-deleted

# 4-seasons.sh — create one daily clip from yesterday's images, sized to its
# share of the corresponding Vivaldi movement's music duration.
#
# On the last day of a movement period, automatically runs montage-mvt.sh to
# compile the full movement montage.
#
# Run once per day from cron (e.g. 01:00 daily).
