Merge branch 'pr-34' (URL encoding) into 0.0.3-draft

Conflicts resolved:
- browse.py: keep both --starts-before and --timezone args
- test_browse.py: combine TestStartsBeforeFilter and TestTimezoneParsing
- SKILL.md: combine documentation for both args

 - `--raw` : Show all events without tradeable filter (for debugging). Includes fetch stats.
 - `--no-cache` : Disable caching and fetch fresh data from the API.
 - `--max-total` : Maximum total events to fetch before early exit. Default: no limit. Useful for quick snapshots.
+- `--starts-before` : Unix timestamp filter. Only show match events starting before this time (LIVE events always shown regardless of timestamp).
+- `--timezone` : Timezone for displaying times. Format: `UTC+X` or `UTC-X` (e.g., `UTC+7`, `UTC-5`). Default: UTC+7 (WIB).
 - `--telegram` : Send results to Telegram. Requires `BOT_TOKEN` and `CHAT_ID` in environment variables.
