chore: bump v0.3.0 build 3 + holiday data + cross-day water dedupe fix

Three things squashed into one commit since they're all release-prep:

1. Bump CFBundleVersion 2 → 3, CFBundleShortVersionString 0.2.0 →
   0.3.0, WorkerPlugin.version & ExpandedView footer string to match.
   Aligns with the 5-feature v0.3.0 ship.

2. fix(water): lastWaterReminderHr was an Int hour (0-23) so a
   yesterday-fired 17:00 blocked today's 17:00 reminder. Now stores
   "yyyy-MM-dd HH" composite key so dedupe is scoped per-day.

3. Holidays.swift: 2026 entry table re-calibrated per typical
   State Council 调休 pattern. Notable changes:
   - 春节 starts on 除夕 02-16 (not 初一 02-17) per 2024 policy
   - 中秋 + 国庆 merged into 10-day 09-25 ~ 10-04 window (since
     2026 中秋 09-25 is 6 days before 国庆 10-01)
   - 劳动节 renamed from "五一" for clarity
   Disclaimer still in header: verify against 国务院 announcement
   when published, edit + re-release if 调休 differs.
