Summary

Prepares the v3.1.0 release notes and a few small corrections on current master. Nothing is tagged or merged.

• Docs now say GitHub App helpers are available from v3.1.0. CHANGELOG.md records that release on 2026-10-21 (GitHub App auth, Laravel 13, Saloon ^4.3, php-jwt ^7, plus the notes that were under Unreleased).
• The changelog workflow checks out and commits to master. It skips the update when the release name or tag already has a changelog heading, so publishing v3.1.0 does not write that entry a second time.
• The PHP constraint is ^8.2, which accepts the same versions as ^8.2|^8.3|^8.4.
• Connector status and 401/403/429 help text use isAuthenticated(), so a strategy such as GitHub App auth is no longer reported as unauthenticated. Covered by tests/Unit/Connectors/GithubConnectorAuthStatusTest.php (failed before the fix, passes after).
• RepoResource usage example calls Github::repos().
• .gitattributes export-ignores dev and agent config (phpstan-bootstrap.php, pint.json, .phpactor.json, .claude).
• docs/ARCHITECTURE.md is a short map of the connector, request, resource, DTO, and auth layout.

Test plan

• vendor/bin/pest — 233 passed, 851 assertions
• vendor/bin/phpstan analyse --memory-limit=512M — no errors
• vendor/bin/pint --test — passed
• Do not tag v3.1.0 from this PR

Ship it.

• Release prep is complete: CHANGELOG, docs, and workflow all updated for v3.1.0 on 2026-10-21.
• GithubConnector now consistently uses isAuthenticated() for strategy-based auth (GitHub App, etc.); new test covers the 401/403/429 paths.
• Composer PHP constraint simplified to ^8.2 (equivalent coverage). .gitattributes and ARCHITECTURE.md are clean additions.
• No tag/merge in this PR, as noted. All checks passed.
