Closes#2102
The @claude mention-triggered workflow fired on issue comments, PR review
comments, PR reviews, and issue open/assign, and each trigger now produces
an Actions run that waits for approval. Copilot handles PR review now, so
the workflow no longer earns the surface area it carries: it was the only
job holding ANTHROPIC_API_KEY, granted a tool-enabled agent Bash, and
needed a fork gate plus an untrusted-checkout carve-out to stay safe.
.mcp.json stays — the workflow passed it via --mcp-config, but it is also
the project-level MCP server config the Claude Code CLI reads locally. The
github-actions Dependabot entry stays too, since main.yml still pins
actions by SHA.
