add VPS snapshot pipeline, run.sh, and data-repair fixesHEADmaster

- fetch_tw_daily.sh: --snapshot mode (one file per trading day, merged by
  symbol), retries, validation of numeric fields
- cron_daily.sh (VPS): lock, pruning, e-mail alerts on failure
- sync_from_vps.sh (Mac): rsync snapshots and merge into per-stock CSVs
- run.sh: pick data files for a symbol, build, analyse, open the page
- lib.sh: LC_ALL=C; fetch.sh: small fixes
- data.rs: repair rows whose open/close fall outside high/low
- template: horizontal hover lines in the RSI and KD panels
