feat: automate repository with GitHub Actions, Docker devcontainer, and modern MCP setup

[Copilot]

Adds best practice GitHub automation (Semgrep, CodeQL, CI, Dependabot), Docker devcontainer with local services (Ollama, SearXNG, SurrealDB), and migrates from JIRA/Linear to GitHub Issues for ticket management.

GitHub Actions

• semgrep.yml - SAST security scanning (weekly + on PRs)
• ci.yml - Lint, typecheck, test, build pipeline
• codeql.yml - Semantic code analysis
• dependabot.yml - Automated dependency updates for npm and actions

DevContainer & Docker

• .devcontainer/devcontainer.json - VS Code container with Node 20, Docker-in-Docker, Copilot extensions
• docker-compose.dev.yml - Local services:
  • Ollama (11434) - LLM inference with OpenAI-compatible API
  • SearXNG (8080) - Privacy-respecting search
  • SurrealDB (8081) - Multi-model database

MCP Configuration

Removed: JIRA, Linear, Notion, Postgres

Added:

{
  "serena": { "command": "uvx", "args": ["--from", "serena-agent", "serena"] },
  "context7": { "command": "npx", "args": ["-y", "@upstash/context7-mcp"] },
  "surrealdb": { "command": "npx", "args": ["-y", "surrealdb-mcp"] },
  "searxng": { "command": "npx", "args": ["-y", "@anthropic/mcp-web-search"] },
  "ollama": { "command": "npx", "args": ["-y", "ollama-mcp"] }
}

Ticket Workflow

/ticket command now uses GitHub Issues:

# Before
/ticket PROJ-123  # JIRA/Linear

# After  
/ticket 42  # GitHub Issue #42 → branch cw/42-feature → PR with "Closes #42"

Supporting Files

• .env.example - Environment configuration template
• .github/copilot-instructions.md - Copilot project guidelines
• Updated README with architecture overview and quick start
