5a3b3d2322 perf(ci): experiment with sccache for relay builds (#5224)
## Summary

- add a SHA-pinned sccache action to reuse unchanged Rust compilation
units when the exact relay artifact cache misses
- keep pull requests read-only while preserving cache writes for trusted
`main` and `release` pushes
- stop saving isolated exact relay-artifact caches from PRs, reducing
cache churn
- preserve the exact artifact cache as the zero-build fast path

## Why this is an experiment

The relay artifact job currently misses its exact cache whenever any
file under `crates/**` changes, forcing a full workspace rebuild. PR
#4975 spent roughly 21 minutes in that job for a one-file `buzz-sdk`
change. sccache targets the relevant reuse boundary—individual compiler
inputs—but the repository cache pool is already under heavy eviction
pressure, so this PR does **not** claim a proven timing win yet.

## Safety

- `Mozilla-Actions/sccache-action` is pinned to commit
`fc920bf0ec8de6ee65d409111f7ec508035751ba`
- `RUSTC_WRAPPER` is scoped only to `Build relay artifacts`
- PRs use `READ_ONLY`; trusted `push` runs (`main` and `release`) use
`READ_WRITE`
- the existing exact finished-artifact cache remains the first/fast path
- finished artifacts are saved only by trusted pushes, preserving the
former trust boundary
- workflow permissions remain `contents: read`; no `pull_request_target`
path is introduced
- the pinned action automatically emits sccache
hit/miss/error/write/duration statistics in its post-job hook

## Validation

- `actionlint .github/workflows/ci.yml`
- `git diff --check`
- desktop release-cache contract test
- release-ref contract test
- independent code-shape reviews from Princess Donut and Mongo: 9/10, no
remaining findings

## Measurement plan

1. purge obsolete PR-scoped `relay-artifacts-*` cache entries before
measurement
2. merge/push a trusted writer to populate sccache
3. run a representative one-crate PR
4. compare relay job duration and automatic sccache statistics against
the 21–22 minute baseline
5. retain this only if the warm run demonstrates material improvement
