Update PR size check workflow (#51948)
## Context

The PR size check workflow has been failing with `403 Resource not
accessible by integration` on every run
([example](https://github.com/zed-industries/zed/actions/runs/23281894554/job/67698634490)).
The root cause is a workflow-level `permissions` block that set a
read-only ceiling, silently preventing the job-level `issues: write` and
`pull-requests: write` grants from taking effect.

This also adds an idempotency improvement: when a new push doesn't
change the PR's size bracket, the workflow now skips the label
remove/re-add cycle, eliminating unnecessary timeline noise.

## How to Review

- Focus on `.github/workflows/pr-size-check.yml` — that's the only file
changed
- Lines 17-23: workflow-level `permissions` block removed, job-level
retained
- Lines 81-112: new `alreadyCorrect` check wraps the label mutation
block

Licensing

License information for third party dependencies must be correctly provided for CI to pass.

We use cargo-about to automatically comply with open source licenses. If CI is failing, check the following:

  • Is it showing a no license specified error for a crate you've created? If so, add publish = false under [package] in your crate's Cargo.toml.
  • Is the error failed to satisfy license requirements for a dependency? If so, first determine what license the project has and whether this system is sufficient to comply with this license's requirements. If you're unsure, ask a lawyer. Once you've verified that this system is acceptable add the license's SPDX identifier to the accepted array in script/licenses/zed-licenses.toml.
  • Is cargo-about unable to find the license for a dependency? If so, add a clarification field at the end of script/licenses/zed-licenses.toml, as specified in the cargo-about book.

Sponsorship

Zed is developed by Zed Industries, Inc., a for-profit company.
