Claude 8617248cc0 Add year-based folders, attribution overlay, notifications, crontab/systemd
season_info.py
- Add ASTRO_YEAR: year of the Winter solstice that started the current cycle
  (Spring/Summer/Autumn 2026 → 2025; Winter Dec-2026 → 2026)

4-seasons.sh
- Daily clip output path now includes ASTRO_YEAR:
  movies/$name/$ASTRO_YEAR/$SEASON/Mvt$N/

montage-mvt.sh (full rewrite)
- Attribution is now a drawtext overlay (top 6 s of the video, fade in/out)
  instead of an appended black card — no frame-size matching needed, and
  year-end join requires no special handling
- Output path mirrors the new year-based folder structure
- Sends notification via notify.sh when done
- Automatically triggers year-end-join.sh after Autumn Mvt 3

year-end-join.sh (new)
- Concatenates all 12 movement montages for a given ASTRO_YEAR
- Output: movies/$name/$ASTRO_YEAR/$name-$ASTRO_YEAR.mp4
- Sends notification when done

notify.sh + notify_config.txt (new)
- Generic best-effort notification helper: ntfy, email, Mattermost text post
- All methods disabled by default; user fills in notify_config.txt

sky-cam.crontab + systemd/ (new)
- Crontab file: sunrise at 09:00, 4-seasons at 01:00, fullday at 02:00
- systemd .service + .timer units for all three daily jobs
- montage/year-end triggered internally, not by cron

# 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).
