feat: add distribution files for Smithery, GitHub Action, and Claude Code Plugin

- Add Claude Code Plugin: plugin.json, .mcp.json, 3 slash commands, skill-builder agent skill
- Add GitHub Action: composite action.yml with 6 inputs/2 outputs, comprehensive README
- Add Smithery: publishing guide with namespace yusufkaraaslan/skill-seekers created
- Add render-mcp.yaml for MCP server deployment on Render
- Fix Dockerfile.mcp: --transport flag (nonexistent) → --http, add dynamic PORT support
- Update AGENTS.md to v3.3.0 with corrected test count and expanded CI section
- Allow distribution/claude-plugin/.mcp.json in .gitignore

+# Skill Seekers — Claude Code Plugin
+
+Transform 17 source types into AI-ready skills and RAG knowledge, directly from Claude Code.
+
+## Installation
+
+### From the Official Plugin Directory
+
+```
+/plugin install skill-seekers@claude-plugin-directory
+```
+
+Or browse for it in `/plugin > Discover`.
+
+### Local Installation (for development)
+
+```bash
+claude --plugin-dir ./path/to/skill-seekers-plugin
+```
+
+### Prerequisites
+
+The plugin requires `skill-seekers` to be installed:
+
+```bash
+pip install skill-seekers[mcp]
+```
+
+## What's Included
+
+### MCP Server (35 tools)
+
+The plugin bundles the Skill Seekers MCP server providing tools for:
+- Scraping documentation, GitHub repos, PDFs, videos, and 13 other source types
+- Packaging skills for 16+ LLM platforms
+- Exporting to vector databases (Weaviate, Chroma, FAISS, Qdrant)
+- Managing configs, workflows, and sources
+
+### Slash Commands
+
+| Command | Description |
+|---------|-------------|
+| `/skill-seekers:create-skill <source>` | Create a skill from any source (auto-detects type) |
+| `/skill-seekers:sync-config <config>` | Sync config URLs against live docs |
+| `/skill-seekers:install-skill <source>` | End-to-end: fetch, scrape, enhance, package, install |
+
+### Agent Skill
+
+The **skill-builder** skill is automatically available to Claude. It detects source types and uses the appropriate MCP tools to build skills autonomously.
+
+## Usage Examples
+
+```
+# Create a skill from a documentation site
+/skill-seekers:create-skill https://react.dev
+
+# Create from a GitHub repo, targeting LangChain
+/skill-seekers:create-skill pallets/flask --target langchain
+
+# Full install workflow with AI enhancement
+/skill-seekers:install-skill https://fastapi.tiangolo.com --enhance
+
+# Sync an existing config
+/skill-seekers:sync-config react
+```
+
+Or just ask Claude naturally:
+> "Create an AI skill from the React documentation"
+> "Scrape the Flask GitHub repo and package it for OpenAI"
+> "Export my skill to a Chroma vector database"
+
+The skill-builder agent skill will automatically detect the intent and use the right tools.
+
+## Remote MCP Alternative
+
+By default, the plugin runs the MCP server locally via `python -m skill_seekers.mcp.server_fastmcp`. To use a remote server instead, edit `.mcp.json`:
+
+```json
+{
+  "skill-seekers": {
+    "type": "http",
+    "url": "https://your-hosted-server.com/mcp"
+  }
+}
+```
+
+## Supported Source Types
+
+Documentation (web), GitHub repos, PDFs, Word docs, EPUBs, videos, local codebases, Jupyter notebooks, HTML files, OpenAPI specs, AsciiDoc, PowerPoint, RSS/Atom feeds, man pages, Confluence, Notion, Slack/Discord exports.
