chore(roo): establish git branching strategy for workshop monorepo

- Add branch naming convention: type/scope/short-description
- Update gitea-push skill: branch guard in Step 1 (never commit to main)
- Update rules-mcp-builder: create branch before any MCP build
- Update rules-bigmind: create branch before any BigMind task
- Update rules-homelab: create branch before any homelab task
- Add Section 11 to REPO_STRATEGY.md: full branching strategy doc
  (types, scopes, workflow, Lumen responsibilities, examples)
- Ticketing decision: Gitea Issues only, no Docker ticketing service

+## Branch Convention
+
+**Never commit directly to `main`.** Every piece of work lives on its own branch.
+
+Format: `type/scope/short-description`
+
+| Type | When |
+|------|------|
+| `feat` | New feature, server, or tool |
+| `fix` | Bug fix |
+| `docs` | Docs, plans, strategy files |
+| `chore` | Refactoring, config, CI, build |
+| `spike` | Experimental / throwaway exploration |
+
+Scope = the affected project area: `bigmind` · `webscraper` · `cannamanage` · `workshop` · `roo` · `plans`

+Examples:
+- `feat/bigmind/people-contacts`
+- `fix/bigmind/health-check-bugs`

 ## Workflow
 
-1. **Check status:**
+1. **Check current branch — branch guard (MANDATORY):**
+   ```bash
+   git branch --show-current
+   ```
+   - If already on a correct feature branch → continue to step 2
+   - If on `main` → **STOP. Create a branch first:**
+     ```bash
+     git checkout -b feat/scope/short-description
+     ```
+   - Never commit to `main`. Not even for "tiny fixes".
+
+2. **Check status:**
    ```bash
    git status
    git diff --stat
    ```
