Fix efficiency and quality issues in triage workflow

Based on comprehensive code review findings, this commit addresses:

CRITICAL FIXES:
- Add explicit parallel execution guidance for Phase 4 analysis (saves 60-80s)
- Make Phases 1a+1b (setup + fetch) run concurrently (saves 10-20s)
- Add Performance Optimization Guidelines section with caching instructions
- Prevent redundant JIRA queries and file reads

HIGH PRIORITY:
- Reduce systemPrompt from ~500 lines to ~15 lines (references triage.md)
- Extract inline JIRA comment format to templates/jira-comment.md
- Add "MUST RUN IN PARALLEL" warnings to prevent sequential execution

Changes:
- workflows/acs-triage/.ambient/ambient.json: Condensed systemPrompt
- workflows/acs-triage/.claude/commands/triage.md: Added performance guidance
- workflows/acs-triage/templates/jira-comment.md: New template file

Benefits:
- Machine-readable parallel execution hints (not just suggestions)
- Clear caching and query batching requirements
- Single source of truth (reduced duplication by ~485 lines)
- Template reuse for JIRA comments

The `/triage` command handles the full pipeline: fetch issues, classify by type, perform specialized analysis, assign teams with confidence scoring, and generate comprehensive reports.\n\n## Workflow Overview\n\nThe `/triage` command executes these phases:\n1. **Setup** - Clone StackRox repo for CODEOWNERS (if needed)\n2. **Fetch** - Query JIRA filter 103399 for untriaged issues (10-20 limit)\n3. **Classify** - Categorize as CI_FAILURE, VULNERABILITY, FLAKY_TEST, or UNKNOWN\n4. **Analyze** - Type-specific analysis (parallel execution for speed)\n5. **Assign** - Multi-strategy team assignment with confidence scoring\n6. **Report** - Generate markdown, HTML, Slack, and JSON outputs\n7. **Comment** - Optionally post analysis to JIRA (only with --comment flag)\n\n## Available Commands\n\n- **/triage** - Complete end-to-end triage pipeline (READ-ONLY)\n- **/triage --comment** - Full triage + post analysis comments to JIRA\n- **/comment-issues** - Standalone command to add comments (requires prior /triage run)\n\n## Team Assignment Strategies\n\nApply in priority order until match found:\n\n1. **CODEOWNERS Match (95% confidence)** - File path → team from CODEOWNERS\n2. **Error Signature Match (85-90%)** - Known error patterns → team\n3. **Service Ownership Match (80%)** - Component/service → team\n4. **Similar Issue History (70-80%)** - JIRA search for resolved similar issues\n5. **Test Category Match (70%)** - Test name → file path → CODEOWNERS\n\n**Confidence Adjustments:**\n- Version mismatch detected: reduce file-path strategies by 20%\n- Multiple strategies agree: use highest confidence\n- No match: \"Needs Manual Assignment\" with evidence\n\n## StackRox/ACS Domain Knowledge\n\n### Teams\n- **@stackrox/core-workflows** - Central service, core platform, GraphQL, API\n- **@stackrox/sensor-ecosystem** - Sensor, SAC implementation, compliance, admission-control\n- **@stackrox/scanner** - Image scanning, vulnerability detection, scanner-v4\n- **@stackrox/collector** - Network monitoring, eBPF, NetworkFlow\n- **@stackrox/install** - Operator, Helm charts, installation\n- **@stackrox/ui** - UI frontend, React, Cypress tests\n\n### Common Error Patterns\n- GraphQL schema validation → @stackrox/core-workflows (90%)\n- panic, FATAL, nil pointer → Extract service from stack trace (85%)\n- dial tcp, connection refused → @stackrox/collector (80%)\n- image pull, scanner errors → @stackrox/scanner (85%)\n- cluster provision, namespace → @stackrox/core-workflows (75%)\n\n## Reference Files\n\nConsult these for domain knowledge:\n- `reference/teams.md` - Team list and responsibilities\n- `reference/CODEOWNERS-patterns.md` - File path → team mappings\n- `reference/error-signatures.md` - Error patterns with confidence scores\n- `reference/team-mappings.md` - Component/service → team ownership\n- `reference/vulnerability-decision-tree.md` - ProdSec workflow\n- `reference/flaky-test-patterns.md` - Known flaky test patterns\n- `reference/constants.md` - Confidence thresholds\n\n## Output Locations\n\nAll artifacts in `artifacts/acs-triage/`:\n- `setup-info.json` - Setup metadata\n- `issues.json` - Complete issue data with enrichments\n- `triage-report.md` - Detailed markdown report\n- `report.html` - Interactive HTML dashboard\n- `slack-summary.md` - Slack notification\n- `summary.json` - Machine-readable summary\n\n## Critical Constraints\n\n1. **READ-ONLY by default** - Use --comment flag to write to JIRA\n2. **Timeout**: 300 seconds (5 minutes) total\n3. **Issue Limit**: 10-20 issues per session\n4. **High Confidence**: ≥80% for auto-assignment recommendations\n5. **Version Awareness**: Detect and adjust for version mismatches\n\n## Best Practices\n\n1. Always check reference files for domain knowledge\n2. Use highest confidence strategy that matches\n3. Document reasoning in reports (team, evidence, confidence)\n4. Flag low confidence (<70%) for manual review\n5. Batch similar issues in reports for efficiency",

+## Performance Optimization Guidelines
+
+**File I/O:**
+- Load `issues.json` ONCE into memory at Phase 3
+- Pass the issues array to all analysis functions
+- Load reference files (CODEOWNERS, error-signatures.md, etc.) once and cache in memory
+
+**JIRA Queries:**
+- Primary fetch: ONE query for filter 103399 (Phase 1b)
+- Similar issue searches (Phase 5): Batch by component, cache results (max 3-5 batched queries)
+- Do NOT query JIRA separately for each issue
+
+**Parallel Execution:**
+- Phase 1a + 1b: Run setup and fetch concurrently
+- Phase 4: Run CI/Vuln/Flaky analysis in parallel (3 concurrent tool calls)
+- Total time savings: 70-100 seconds vs sequential execution

 ## Notes
 
 - **Timeout**: 300 seconds total (5 minutes)
 - **Issue Limit**: 10-20 issues to stay within timeout
