The FetchMergeQueue function was hardcoded to query PRs from
michaellady/roxas and michaellady/gastown, causing the dashboard
to show unrelated PRs regardless of which rigs are actually registered.
This fix:
- Adds townRoot to LiveConvoyFetcher to access workspace config
- Loads registered rigs from mayor/rigs.json dynamically
- Adds gitURLToRepoPath helper to convert git URLs (HTTPS/SSH) to
owner/repo format for the gh CLI
- Updates comments to reflect the new behavior
