feat(marketplace): command consolidation + 8 new plugins (v8.1.0 → v9.0.0) [BREAKING]

Phase 1b: Rename all ~94 commands across 12 plugins to /<noun> <action>
sub-command pattern. Git-flow consolidated from 8→5 commands (commit
variants absorbed into --push/--merge/--sync flags). Dispatch files,
name: frontmatter, and cross-reference updates for all plugins.

Phase 2: Design documents for 8 new plugins in docs/designs/.

Phase 3: Scaffold 8 new plugins — saas-api-platform, saas-db-migrate,
saas-react-platform, saas-test-pilot, data-seed, ops-release-manager,
ops-deploy-pipeline, debug-mcp. Each with plugin.json, commands, agents,
skills, README, and claude-md-integration. Marketplace grows from 12→20.

+## Purpose
+
+Create a git commit with an auto-generated conventional commit message. Optionally push, merge, or sync in the same operation.
+
+## Parameters
+
+| Parameter | Description |
+|-----------|-------------|
+| `--message`, `-m` | Override auto-generated message |
+| `--all`, `-a` | Stage all changes before commit |
+| `--push` | After commit: push to remote (replaces former `/git-commit-push`) |
+| `--merge [target]` | After commit: merge into target branch (replaces former `/git-commit-merge`) |
+| `--sync` | After commit: push and sync with base branch (replaces former `/git-commit-sync`) |
+| `--force` | Force push (with --push or --sync, requires confirmation) |
+| `--squash` | Squash commits on merge (with --merge) |
+| `--no-delete` | Keep branch after merge (with --merge) |
+| `--base` | Override default base branch (with --sync) |
+| `--no-rebase` | Use merge instead of rebase (with --sync) |
+
+## Workflow
+
+### Base: Commit
+1. **Display header** — GIT-FLOW Smart Commit
+2. **Check protected branch** — per git-safety.md
+3. **Analyze changes** — `git status` and `git diff --staged`
+4. **Handle unstaged** — Prompt to stage if nothing staged
+5. **Generate message** — Create conventional commit (per commit-conventions.md)
+6. **Confirm or edit** — Present message with options
+7. **Execute commit**
+
+### Flag: --push
+8. **Check upstream** — Set up tracking if needed
+9. **Push to remote**
+10. **Handle conflicts** — Offer rebase/merge/force if push fails
+
+### Flag: --merge
+8. **Identify target** — Prompt for target branch if not specified
+9. **Select strategy** — Merge commit, squash, or rebase (per merge-workflow.md)
+10. **Execute merge** — Switch to target, pull, merge, push
+11. **Handle conflicts** — Guide resolution
+12. **Cleanup** — Offer to delete merged branch
+
+### Flag: --sync
+8. **Push committed changes**
+9. **Fetch with prune** — `git fetch --all --prune`
+10. **Sync with base** — Rebase on base branch (per sync-workflow.md)
+11. **Handle conflicts** — Guide resolution (per merge-workflow.md)
+12. **Push again** — `git push --force-with-lease` if rebased
+13. **Report stale branches**
+
+## Flag Mutual Exclusivity
+
+`--push`, `--merge`, and `--sync` are mutually exclusive. If multiple are provided, error with:
+"Only one of --push, --merge, or --sync may be specified."
+
+## Output
+
+### Base commit:
+```
+Committed: abc1234
+feat(auth): add password reset functionality
+```
+
+### With --push:
+```
+Committed: abc1234
+Pushed to: origin/feat/password-reset
+```
+
+### With --merge:
+```
+Committed: abc1234
+Merged feat/password-reset -> development
+```
+
+### With --sync:
+```
+Committed: abc1234
+Pushed to: origin/feat/password-reset
+Synced with: development
+```
