feat(error-tracking): add --state, --team, --assignee filters to issues search

[platinummonkey]

Summary

Exposes new filter parameters on pup error-tracking issues search from SDK PRs #1568 and #1480.

Changes

• src/commands/error_tracking.rs — add state, team, assignee params to issues_search; map state string → IssueState enum; accept team/assignee as UUIDs; update all existing call sites to pass None for new params
• src/main.rs — add --state, --team, --assignee optional args to ErrorTrackingIssueActions::Search; thread through to dispatch call
• docs/COMMANDS.md — document new flags

New flags

--state <STATE>     Filter by issue state: OPEN, ACKNOWLEDGED, RESOLVED, IGNORED, EXCLUDED
--team <UUID>       Filter by team UUID assignee
--assignee <UUID>   Filter by user UUID assignee

These are independent of the existing --track/--persona mutual exclusion.

Testing

• test_issues_search_with_state — happy path with state=OPEN
• test_issues_search_invalid_state — rejects unknown state values
• test_issues_search_invalid_team_uuid — rejects non-UUID team input
• test_issues_search_invalid_assignee_uuid — rejects non-UUID assignee input
• test_error_tracking_clap_state_accepted — clap accepts --state alongside --track
