Add unit tests for various components and stores in the terminal dashboard

- Implement tests for AssociationHighlight, DashboardToolbar, QueuePanel, SessionGroupTree, and TerminalDashboardPage to ensure proper functionality and state management.
- Create tests for cliSessionStore, issueQueueIntegrationStore, queueExecutionStore, queueSchedulerStore, sessionManagerStore, and terminalGridStore to validate state resets and workspace scoping.
- Mock necessary dependencies and state management hooks to isolate tests and ensure accurate behavior.

+## TASK ASSIGNMENT
+
+### MANDATORY FIRST STEPS
+1. Read shared discoveries: {session_folder}/discoveries.ndjson (if exists, skip if not)
+2. Read project context: .workflow/project-tech.json (if exists)
+3. Read task schema: .codex/skills/team-arch-opt/schemas/tasks-schema.md
+

+
+## Your Task
+
+**Task ID**: {id}
+**Title**: {title}
+**Description**: {description}
+**Role**: {role}
+**Issue Type**: {issue_type}
+**Priority**: {priority}
+**Target Files**: {target_files}
+
+### Previous Tasks' Findings (Context)

+
+## Execution Protocol
+
+1. **Read discoveries**: Load {session_folder}/discoveries.ndjson for shared exploration findings
+2. **Use context**: Apply previous tasks' findings from prev_context above
+3. **Execute by role**:
+
+   **If role = analyzer**:
+   - Scan codebase for architecture issues within target scope
+   - Build import/require graph, detect circular dependencies
+   - Identify God Classes (>500 LOC, >10 public methods)
+   - Calculate coupling (fan-in/fan-out) and cohesion metrics
+   - Detect dead code, dead exports, layering violations
+   - Collect quantified baseline metrics
+   - Rank top 3-7 issues by severity (Critical/High/Medium)
+   - Write `{session_folder}/artifacts/architecture-baseline.json` (metrics)
+   - Write `{session_folder}/artifacts/architecture-report.md` (ranked issues)
+
+   **If role = designer**:
+   - Read architecture report and baseline from {session_folder}/artifacts/
+   - For each issue, select refactoring strategy by type:
+     - CYCLE: interface extraction, dependency inversion, mediator
+     - GOD_CLASS: SRP decomposition, extract class/module
+     - COUPLING: introduce interface/abstraction, DI, events
+     - DUPLICATION: extract shared utility/base class
+     - LAYER_VIOLATION: move to correct layer, add facade
+     - DEAD_CODE: safe removal with reference verification
+     - API_BLOAT: privatize internals, barrel file cleanup
+   - Prioritize by impact/effort: P0 (high impact+low effort) to P3 (low impact or high effort)
+   - Assign unique REFACTOR-IDs (REFACTOR-001, 002, ...) with non-overlapping file targets
+   - Write `{session_folder}/artifacts/refactoring-plan.md`
+
+   **If role = refactorer**:
+   - Read refactoring plan from {session_folder}/artifacts/refactoring-plan.md
+   - Apply refactorings in priority order (P0 first)
+   - Preserve existing behavior -- refactoring must not change functionality
+   - Update ALL import references when moving/renaming modules
+   - Update ALL test files referencing moved/renamed symbols
+   - Verify no dangling imports after module moves
+
+   **If role = validator**:
+   - Read baseline from {session_folder}/artifacts/architecture-baseline.json
+   - Read plan from {session_folder}/artifacts/refactoring-plan.md
+   - Build validation: compile/type-check, zero new errors
+   - Test validation: run test suite, no new failures
+   - Metric validation: coupling improved or neutral, no new cycles
+   - API validation: public signatures preserved, no dangling references
+   - Write `{session_folder}/artifacts/validation-results.json`
+   - Set verdict: PASS / WARN / FAIL
+
+   **If role = reviewer**:
+   - Read plan from {session_folder}/artifacts/refactoring-plan.md
+   - Review changed files across 5 dimensions:
+     - Correctness: no behavior changes, all references updated
+     - Pattern consistency: follows existing conventions
+     - Completeness: imports, tests, configs all updated
+     - Migration safety: no dangling refs, backward compatible
+     - Best practices: SOLID, appropriate abstraction
+   - Write `{session_folder}/artifacts/review-report.md`
+   - Set verdict: APPROVE / REVISE / REJECT
+
+4. **Share discoveries**: Append exploration findings to shared board:
+   ```bash
+   echo '{"ts":"<ISO8601>","worker":"{id}","type":"<type>","data":{...}}' >> {session_folder}/discoveries.ndjson
+   ```
+5. **Report result**: Return JSON via report_agent_job_result
+
+### Discovery Types to Share
