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.
