chore(docs): update AGENTS.md to reflect recent changes

[RedStar071]

🔗 Linked issue

N/A — routine AGENTS.md maintenance.

🧭 Context

This is the weekly automated review of AGENTS.md against pull requests merged into main in the last 7 days (2026-08-17 to 2026-08-24).

📚 Description

Two PRs merged in the window:

• ci: add pkg.pr.new continuous release workflow #48 (ci: add pkg.pr.new continuous release workflow) adds .github/workflows/pkg-pr-new.yml, a new CI workflow that publishes preview packages to pkg.pr.new on every branch push. AGENTS.md already documents the other CI workflows (ci.yml, release.yml, documentation.yml) and their runner choices, so this new workflow was missing from that coverage.
• ci(release): authenticate snapshot changelog #45 (ci(release): authenticate snapshot changelog) only changes .changeset/README.md and release.yml internals (exposing WOLFSTAR_TOKEN as GITHUB_TOKEN for the snapshot changelog generator); AGENTS.md doesn't document secret wiring at that level of detail and already just points to .changeset/README.md, so no gap there.

Key changes

Aspect	Before	After
CI runner note (Gotchas)	Listed ci.yml / release.yml runners only	Also notes pkg-pr-new.yml runs on ubuntu-24.04-arm
Gotchas	No mention of preview releases	New bullet documenting that every branch push publishes preview packages via pkg-pr-new.yml to pkg.pr.new

Type of Change

• New feature (non-breaking change which adds functionality)
• Bug fix (non-breaking change which fixes an issue)
• Breaking change (fix or feature that would cause existing functionality to not work as expected)
• Documentation change
• Workflow / CI change

Pre-flight Checklist

• I have read the Contributing Guidelines (if applicable)
• My code follows the code style of this project
• I have added tests that prove my fix is effective or that my feature works
• New and existing unit tests pass locally with my changes
• I have updated the documentation accordingly
• I added a changeset with pnpm changeset (or pnpm changeset add --empty if no release is needed) — not needed, this is a docs-only change to a file outside packages/, matching the precedent set by docs: update AGENTS.md to reflect recent changes #31 and docs: update AGENTS.md to reflect recent changes #44.

Note

Update AGENTS.md to document CI runners and pkg.pr.new workflow

• Notes that ubuntu-24.04-arm is used for ci.yml and pkg-pr-new.yml, while ubuntu-latest is used for release.yml
• Documents that every push triggers builds and publishes preview tarballs to pkg.pr.new via pnpm exec pkg-pr-new publish
