Skill Seeker MCP Server (FastMCP Implementation)

Modern, decorator-based MCP server using FastMCP for simplified tool registration.
Provides 17 tools for generating Claude AI skills from documentation.

This is a streamlined alternative to server.py (2200 lines → 708 lines, 68% reduction).
All tool implementations are delegated to modular tool files in tools/ directory.

**Architecture:**
- FastMCP server with decorator-based tool registration
- 17 tools organized into 5 categories:
  * Config tools (3): generate_config, list_configs, validate_config
  * Scraping tools (4): estimate_pages, scrape_docs, scrape_github, scrape_pdf
  * Packaging tools (3): package_skill, upload_skill, install_skill
  * Splitting tools (2): split_config, generate_router
  * Source tools (5): fetch_config, submit_config, add_config_source, list_config_sources, remove_config_source

**Usage:**
  # Stdio transport (default, backward compatible)
  python -m skill_seekers.mcp.server_fastmcp

  # HTTP transport (new)
  python -m skill_seekers.mcp.server_fastmcp --http
  python -m skill_seekers.mcp.server_fastmcp --http --port 8080

**MCP Integration:**
  Stdio (default):
  {
    "mcpServers": {
      "skill-seeker": {
        "command": "python",
        "args": ["-m", "skill_seekers.mcp.server_fastmcp"]
      }
    }
  }

  HTTP (alternative):
  {
    "mcpServers": {
      "skill-seeker": {
        "url": "http://localhost:8000/sse"
      }
    }
