Add Q workflow for agentic workflow optimization

[Copilot]

Ports the Q workflow from githubnext/gh-aw, adapting it to use builtin tools rather than external MCP servers.

Changes

Workflow Implementation (workflows/q.md)

• Replace gh-aw MCP server with builtin agentic-workflows tool
• Replace Serena (code analysis) → bash + edit tools
• Replace Tavily (web search) → web-search tool
• Remove .lock.yml compilation references
• Update paths: .github/workflows/ → workflows/
• Generalize prompt instructions to be framework-agnostic

Documentation

• Add docs/q.md following repository conventions
• Update README.md to list Q under analysis workflows

What Q Does

Analyzes workflow execution logs to identify:

• Missing tool declarations
• Permission errors
• Repetitive tool call patterns
• Performance bottlenecks

Creates PRs with targeted fixes when invoked via /q command on issues/PRs.

Example Usage

/q Analyze all workflows and suggest optimizations
/q Fix missing tools in the daily-progress workflow

Original prompt

Add a copy of the Q agentic workflow from githubnext/gh-aw in the workflow folder .

Make the prompt more generic as it is not meant to run in gh-aw anymore and should use the builtin tool agentic-workflows instead of the shared agentic workflow.

If needed migrate shared agentic workflow for Serena as well.
