Subject: [PATCH 1/2] feat: add build documentation verification tool
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Adds verify_build.py - a Python tool that parses Dasharo building-manual
markdown pages, extracts build commands, and runs them in a Docker container
with the coreboot SDK to verify the documentation produces the same binary
as the published release.

Supports:
- Device registry mapping slugs → repos, targets, ROM patterns
- Markdown code block extraction with shell/bash/language-agnostic parsing
- Docker-based build execution with coreboot/coreboot-sdk
- SHA256 hash computation for binary comparison
- CLI interface: --device/--release for single, --all for batch, --dry-run for parsing only

Closes #1153

Subject: [PATCH 2/2] feat: add GitHub Actions workflow for build documentation
 verification

Adds .github/workflows/verify-build-docs.yml that:
- Runs on PRs that modify building-manual files
- Runs weekly on a schedule (Monday 6am UTC)
- Discovers all building-manual.md files in the repo
- Parses build commands from markdown code blocks
- Reports parse results and validates command extraction

Closes #1153
