Christian Byrne 6689a1b14e fix: split perf report workflow for fork PR support (#9382)
## Summary

Perf report workflow fails on fork PRs because `GITHUB_TOKEN` is
read-only for forks, causing "Resource not accessible by integration" on
the PR comment step.

## Changes

- **What**: Split `ci-perf-report.yaml` into a data-collection workflow
+ a `workflow_run`-triggered reporter (`pr-perf-report.yaml`), matching
the existing `ci-size-data`/`pr-size-report` pattern. Added fork PR
permissions guidance to `.github/AGENTS.md`.
- **ci-perf-report.yaml**: Removed the `report` job and `pull-requests:
write` permission. Added PR metadata (number + base branch) artifact
upload.
- **pr-perf-report.yaml** (new): Triggered by `workflow_run` on the perf
workflow. Downloads metrics + metadata artifacts, generates report,
posts PR comment with write permissions from the default-branch context.

## Review Focus

- The two-workflow split follows the same pattern as `ci-size-data.yaml`
→ `pr-size-report.yaml`, which already works for fork PRs.
- The `workflow_run` trigger runs in the base repo context per [GitHub
Security Lab
guidance](https://securitylab.github.com/resources/github-actions-preventing-pwn-requests/),
so it safely has write permissions even for fork PRs.
- AGENTS.md guidance documents this pattern to prevent recurrence.

# PR Review Context
Context for automated PR review system.
## Review Scope
This automated review performs comprehensive analysis:
- Architecture and design patterns
- Security vulnerabilities
- Performance implications
- Code quality and maintainability
- Integration concerns
For implementation details, see `.claude/commands/comprehensive-pr-review.md`.
## GitHub Actions: Fork PR Permissions
Fork PRs get a **read-only `GITHUB_TOKEN`** — no PR comments, no secret access, no pushing.
Any workflow that needs write access must use the **two-workflow split**: a `pull_request`-triggered `ci-*.yaml` uploads artifacts (including PR metadata), then a `workflow_run`-triggered `pr-*.yaml` downloads them and posts comments with write permissions. See `ci-size-data``pr-size-report` or `ci-perf-report``pr-perf-report`. Use `.github/actions/post-pr-report-comment` for the comment step.
Never write PR comments directly from `pull_request` workflows or use `pull_request_target` to run untrusted code.
