feat: implement mcpctl install command with LLM-assisted auto-config

Add install command for setting up MCP servers with:
- Server lookup by name/package from registry search results
- LLM-assisted README analysis for missing envTemplate (Ollama)
- Interactive credential prompting with password masking
- Non-interactive mode using env vars for CI/CD
- Dry-run mode, custom profile names, project association
- Zod validation of LLM responses, README sanitization
- DI for full testability, 38 tests

128 tests passing total.
