Sorry, something went wrong.
Switch the trigger from pull_request_target to pull_request and drop the write permissions. GitHub now refuses to check out fork PR code from a pull_request_target workflow, breaking formatting checks for external contributors. See QuantumKitHub/.github#2.

Switches the Format workflow trigger from pull_request_target to
pull_request and drops the actions: write / pull-requests: write
permissions.
GitHub now refuses to check out fork PR code from a pull_request_target
workflow, which broke the formatting check for all external contributors
(PRs from forks). The reusable workflow has been reworked to run safely under a
read-only pull_request context and reports the formatting diff in the job
summary instead of commenting on the PR.
Depends on QuantumKitHub/QuantumKitHubActions#2 (the reusable workflow update),
which should be merged first since this references FormatCheck.yml@main.
