fix(team): use session-id instead of team-name in team_msg across all skills

Root cause: team_msg --team parameter maps directly to filesystem path
.workflow/.team/{value}/.msg/, so using team-name creates wrong directory.

Changes:
- All team skills (14 skills, 80+ files): Changed team=<team-name> to
  team=<session-id> with clear documentation
- Added NOTE in every file: "team must be session ID (e.g., TLS-xxx-date),
  NOT team name. Extract from Session: field in task description."
- CLI fallback examples updated: --team brainstorm -> --team <session-id>

Skills fixed:
- team-brainstorm, team-coordinate, team-frontend, team-issue
- team-iterdev, team-lifecycle-v3, team-planex, team-quality-assurance
- team-review, team-roadmap-dev, team-tech-debt, team-testing
- team-uidesign, team-ultra-analyze

Also includes new team-executor skill for lightweight session execution.

+# Reviewer — Phase 2-4
+
+## Phase 2: Mode Detection
+
+| Task Prefix | Mode | Dimensions | Inline Discuss |
+|-------------|------|-----------|---------------|
+| REVIEW-* | Code Review | quality, security, architecture, requirements | None |
+| QUALITY-* | Spec Quality | completeness, consistency, traceability, depth, coverage | DISCUSS-006 |
+| IMPROVE-* | Spec Quality (recheck) | Same as QUALITY | DISCUSS-006 |
+
+## Phase 3: Review Execution
+
+### Code Review (REVIEW-*)
+
+**Inputs**: Plan file, git diff, modified files, test results (if available)
+
+**4 dimensions**:
+
+| Dimension | Critical Issues |
+|-----------|----------------|
+| Quality | Empty catch, any in public APIs, @ts-ignore, console.log |
+| Security | Hardcoded secrets, SQL injection, eval/exec, innerHTML |
+| Architecture | Circular deps, parent imports >2 levels, files >500 lines |
+| Requirements | Missing core functionality, incomplete acceptance criteria |
+
+### Spec Quality (QUALITY-* / IMPROVE-*)
+
+**Inputs**: All spec docs in session folder, quality gate config
+
+**5 dimensions**:
+
+| Dimension | Weight | Focus |
+|-----------|--------|-------|
+| Completeness | 25% | All sections present with substance |
+| Consistency | 20% | Terminology, format, references |
+| Traceability | 25% | Goals -> Reqs -> Arch -> Stories chain |
+| Depth | 20% | AC testable, ADRs justified, stories estimable |
+| Coverage | 10% | Original requirements mapped |
+
+**Quality gate**:
+
+| Gate | Criteria |
+|------|----------|
+| PASS | Score >= 80% AND coverage >= 70% |
+| REVIEW | Score 60-79% OR coverage 50-69% |
+| FAIL | Score < 60% OR coverage < 50% |
+
+**Artifacts**: readiness-report.md + spec-summary.md
+
+## Phase 4: Verdict + Inline Discuss
+
+### Code Review Verdict
+
+| Verdict | Criteria |
+|---------|----------|
+| BLOCK | Critical issues present |
+| CONDITIONAL | High/medium only |
+| APPROVE | Low or none |
+
+### Spec Quality Inline Discuss (DISCUSS-006)
+
+After generating readiness-report.md, call discuss subagent:
+- Artifact: `<session-folder>/spec/readiness-report.md`
+- Round: DISCUSS-006
+- Perspectives: product, technical, quality, risk, coverage (all 5)
+
+Handle discuss verdict per team-worker consensus handling protocol.
+
+> **Note**: DISCUSS-006 HIGH always triggers user pause (final sign-off gate), regardless of revision count.
+
+**Report**: mode, verdict/gate, dimension scores, discuss verdict (QUALITY only), output paths.
+
+## Error Handling
+
+| Scenario | Resolution |
+|----------|------------|
+| Missing context | Request from coordinator |
+| Invalid mode | Abort with error |
+| Analysis failure | Retry, then fallback template |
+| Discuss subagent fails | Proceed without final discuss, log warning |
