docs: add a Tooling section for utilities that work with AGENTS.md

[zackabrah]

Disclosure: I'm the author of Scopeglass.

The site lists agents that consume the AGENTS.md format, but no supporting
tooling yet. This adds a small "Tooling" section (matching the AboutSection
component style) with one entry:

• Scopeglass — local CLI that
  shows the effective AGENTS.md chain for any path: precedence order,
  line-level provenance, context-size estimates, and checks for broken
  references, duplicates, and conflicting guidance. Includes a CI gate
  (scopeglass check).

No network calls, no model calls, MIT. Happy to trim this to a single FAQ
line instead if a dedicated section feels premature.

npx tsc --noEmit passes. pnpm-lock.yaml untouched.

A member of the Team first needs to authorize it.

Hi guys, I'm the author of Syngraphe.

I like the idea of keeping this as a general Tooling section rather than making it specific to one project.

Syngraphe might also fit here: https://github.com/suffro/syngraphe

It's a small Git-native CLI for keeping structured repository context behind AGENTS.md. It creates a .context/ directory for stable project knowledge, current state, decisions and history, while AGENTS.md acts as the entry point for coding agents.

The context remains plain Markdown owned by the repository, and syngraphe check provides deterministic integrity checks for missing files, broken references and drift in the managed AGENTS.md bootstrap.

Happy to submit a small follow-up PR adding it if this Tooling section is accepted.

You were not the author of this. I am the author of this. I have done all my own work you've done nothing except barnacle and suck off of my information. Get off my stuff.
