Multiple CLI commands had a systematic bug where ResolveID responses were
incorrectly converted using string(resp.Data) instead of json.Unmarshal.
Since resp.Data is json.RawMessage (already JSON-encoded), this preserved
the JSON quotes, causing IDs to become "bd-1048" instead of bd-1048.
When re-marshaled for subsequent RPC calls, these became double-quoted
("\"bd-1048\""), causing database lookups to fail.
Bugs fixed:
1. Nil pointer dereference in handleShow - added nil check after GetIssue
2. Double JSON encoding in 12 locations across 4 commands:
- bd show (3 instances in show.go)
- bd dep add/remove/tree (5 instances in dep.go)
- bd label add/remove/list (3 instances in label.go)
- bd reopen (1 instance in reopen.go)
All instances replaced string(resp.Data) with proper json.Unmarshal.
Removed debug logging added during investigation.
Tested: All affected commands now work correctly with daemon mode.
