Neil 08bf209e40 fix(ci): run PR LoC scripts from the default branch, not PR head (#15016)
The PR test LoC job fetched .github/scripts/pr-test-loc-*.mjs from
pull/<n>/head and ran them with node while holding a GITHUB_TOKEN scoped
pull-requests: write, so PR-authored code executed under a write token.

Pin the fetch to the repository default branch. base.sha is not enough:
for stacked PRs it is an unreviewed feature-branch commit any collaborator
can push to, while main is gated by branch protection.

Also pass event data via env instead of shell interpolation, and add
set -euo pipefail so a failed download cannot leave a truncated script.

# Why no checkout: the Files API already has per-file additions/deletions.
# Why the default branch and never pull/<n>/head: this job holds a write-scoped
# GITHUB_TOKEN, so it may only execute reviewed code. A PR that edits these
# scripts takes effect once merged.
