feat(/bounty): add pagination, sorting, and filtering

- Default shows 5 bounties per page
- /bounty 10 - show 10 bounties
- /bounty all - show all active (exclude overdue >24h)
- /bounty all 10 - show 10 including expired

Filtering:
- Overdue >24h filtered out by default
- 'all' flag includes overdue

Sorting:
- Bounties with due date sorted by due_date_ts (earliest first)
- Bounties without due date shown last, sorted by created_at

Output format updated:
- Header shows 'Showing X of Y bounties'
- Description sliced to 40 chars when showing pagination info
- Date format changed to '4 Apr 2026' style

Fixes #48
