[PATCH 04/23] rteval: mcp-server: Add Claude Code plugin configuration

Add plugin manifest and configuration files to enable the rteval MCP
server as a Claude Code plugin. This allows conversational querying and
analysis of rteval test results through Claude Code.

Changes:
- Add .claude-plugin/plugin.json with MCP server configuration
- Add manifest.json with plugin metadata
- Add test_tools.py to validate all MCP tools work correctly
- Update README.md with installation and usage instructions

The plugin provides 5 tools for rteval result analysis:
- list_results: Find rteval XML result files
- parse_result: Extract metrics from a single result
- compare_results: Compare two test runs with deltas
- list_logs: List stdout/stderr logs from a test run
- read_log: Read logs with head/tail/grep filtering

After restart, tools are available with the prefix:
mcp__plugin_rteval-mcp_rteval__

 ## Installation
 
+On Fedora:
 ```bash
-pip install -r requirements.txt
+sudo dnf install python3-mcp python3-mcp+cli python3-lxml
 ```
 
+## Available Tools
+
+- **list_results**: List rteval result files in a directory
+- **parse_result**: Parse an rteval XML result file and extract key metrics
+- **compare_results**: Compare two rteval result files side-by-side
+- **list_logs**: List available log files in an rteval result directory
+- **read_log**: Read log content with optional filtering (head/tail/grep)
+
 ## Usage
 
-TBD - Server configuration and client usage instructions to be added.
+### Testing the Server Directly
+
+```bash
+python3 test_tools.py
+```
+
+### Using with Claude Code
+
+The server is configured as a Claude Code plugin. After installation:
+
+1. The server is registered in `~/.claude/plugins/installed_plugins.json`
+2. Enabled in `~/.claude/settings.json`
+3. Restart Claude Code to load the plugin
+4. Tools will be available with the prefix: `mcp__plugin_rteval-mcp_rteval__`
+
+Example:
+```
+list rteval results in ~/src/rteval
+```
+
+### Using with MCP Inspector
+
+```bash
+mcp dev server.py
+```
