Add auto_merge_local option for local-only contracts (#50)

When local_only=true on a contract, all completion actions are skipped.
This adds a new option auto_merge_local that, when enabled along with
local_only, will automatically merge completed task changes to the
master/main branch locally (without pushing or creating PRs).

Changes:
- Add auto_merge_local column to contracts table (migration)
- Add auto_merge_local field to Contract model and summary
- Update CreateContractRequest and UpdateContractRequest structs
- Update contract repository create/update functions
- Add auto_merge_local to WebSocket protocol StartTask command
- Pass auto_merge_local through spawn_task and run_task functions
- Modify task manager completion logic: if local_only=true AND
  auto_merge_local=true, execute 'merge' completion action locally
- Update all server handlers to retrieve and pass auto_merge_local
- Add TypeScript types to frontend components
