Integrate bug fix/triage tool into BugBug

[suhaibmujahid]

For now, it runs via CLI; I'll follow up by creating a cloud-based service.

Pull request overview

This PR integrates the Larrey bug-triage/fix workflow into BugBug as a locally runnable CLI tool, and adds a new “duplicate_bugs” agent with associated prompts/config to support duplicate detection workflows.

Changes:

• Add a CLI entry script to run the bug-fix triage agent locally (dry-run, verbose) with Pydantic CLI/env settings.
• Introduce Bugzilla + Firefox in-process MCP servers and Firefox evaluation/build helpers to support triage investigation.
• Add a new duplicate-bugs tool (agent + prompts + config) and ensure prompt/rule artifacts are packaged in wheels.
