feat(roo): add Patrick-persona custom modes, skills, and mode-specific rules

Add 4 new custom modes with BigMind guidance:
- rules-bigmind/: Introspective Patrick mode (BigMind development)
- rules-homelab/: Tinkerer Patrick mode (TrueNAS, Docker, infra)
- rules-mcp-builder/: Craftsman Patrick mode (pi_mcps MCP servers)
- rules-paisy/: Professional Patrick mode (ADP Germany payroll)

Add reusable skills:
- skills/assessment-first/: structured assessment.md before implementation
- skills/bigmind-session-ritual/: mandatory session start/end ritual
- skills/gitea-push/: conventional commit + Gitea push workflow
- skills/new-mcp-server/: FastMCP scaffold procedure
- skills-bigmind/, skills-homelab/, skills-mcp-builder/, skills-paisy/: mode-specific skill dirs

Update existing rules:
- rules-architect, rules-ask, rules-code, rules-debug, rules-orchestrator:
  add BigMind session guidance (search before task, announce focus, hypotheses)

+# Homelab Mode Behavior — Roo Code
+
+## Active Persona: Tinkerer Patrick
+
+Patrick is in homelab mindset. He is experimenting, building, and maintaining his personal infrastructure ecosystem. No corporate constraints — full admin rights on everything.
+
+## Infrastructure Context (always active in this mode)
+
+| Asset | Details |
+|-------|---------|
+| Workstation | Fedora Linux, Ryzen 5900X, RX 7900 XTX (24GB VRAM), 8TB NVMe |
+| Server | TrueNAS.local @ 192.168.188.119, Ryzen 5900X, Docker, 1.2TB SSD pool |
+| Gitea | http://192.168.188.119:30008/ — homelab git server, source of truth |
+| AI | Ollama (local models), Grok Code (prepaid), Claude Code ($50 prepaid) |
+| MCP base | ~/pi_mcps/ — all MCP servers live here |
+
+## Before Starting Any Homelab Task
+1. **Search Infrastructure Facts:** `memory_search_facts("TrueNAS Docker")` + `memory_search_facts("Gitea homelab")`
+2. **Check for Existing MCP Server:** Does a pi_mcps server already handle this task? Check before building ad-hoc
+3. **Announce Focus:** `memory_announce_focus(session_id, "Homelab: X", files=["docker-compose.yml"], ide_hint="VS Code")`
+4. **Form Hypothesis:** `memory_add_hypothesis(session_id, "This service will run on TrueNAS Docker with X config")`
+
+## Homelab Coding Patterns
+- **Prefer Docker Compose** over ad-hoc docker run commands
+- **CLI-first:** Prefer terminal solutions over GUI navigation
+- **Paths:** Everything on TrueNAS lives under /mnt/ (ZFS datasets). Workstation workspace: ~/pi_mcps/
+- **Networking:** Direct LAN access — no VPN/firewall between workstation and TrueNAS.local
+- **Local AI:** When using Ollama, check VRAM headroom (RX 7900 XTX = 24GB). ROCm stack on Fedora
+- **uv for Python:** Never use pip directly on the workstation
+
+## Gitea Workflow
+- Push all homelab repos to Gitea first
+- PAT stored in BigMind (fact id 93) — never commit tokens to code
+- Conventional commit format: `type(scope): description`
+
+## After Homelab Changes
+1. **Store Infrastructure Fact:** `memory_store_fact("environment-config", "Service X running on TrueNAS at port Y with config Z")`
+2. **Commit to Gitea:** Use conventional commits, push to homelab Gitea
+3. **Resolve Hypothesis:** Update based on what actually worked
