fix: add --repo to serve so get_docs_section works via uvx

[lbzepoqo]

Problem

get_docs_section_tool always returns {"status": "not_found"} when the MCP server runs via uvx. The root cause is that the existing auto-detection relies on the current working directory being inside the repo, which is not the case under uvx.

The serve subcommand was also the only one without a --repo argument — every other subcommand (build, update, watch, status, visualize, install, init) accepts --repo for explicit repo root specification.

Solution

Add --repo to the serve subcommand, consistent with all other subcommands. Thread the value through main() via a module-level default, then pass it to get_docs_section so the tool can locate docs/LLM-OPTIMIZED-REFERENCE.md.

No files are bundled into the wheel — docs stay in docs/ in the source tree.

Usage

# Standard install via uvx — now works correctly:
uvx code-review-graph serve --repo /path/to/your/repo

In .mcp.json:

{
  "mcpServers": {
    "code-review-graph": {
      "command": "uvx",
      "args": ["code-review-graph", "serve", "--repo", "/path/to/your/repo"]
    }
  }
}

Changes

File	Change
code_review_graph/cli.py	Add --repo to serve subparser; pass to serve_main()
code_review_graph/main.py	Accept repo_root in main(); store as module-level default; pass to get_docs_section
code_review_graph/tools.py	Add repo_root param to get_docs_section; use explicit path first, then auto-detect

Test Plan

• uv run --with pytest pytest — 111 passed
• get_docs_section('troubleshooting', repo_root='.') returns section content
• code-review-graph serve --help shows --repo option
