ci: optimize workflow caching and checkouts (#29874)

<!--
Please submit this PR as a draft initially.

Do not mark it as "Ready for review" until this PR meets the canonical
Definition of Ready For Review in `docs/readme/ready-for-review.md`.

In short: the template must be materially complete (not just section
titles
present), all status checks must be currently passing, and the only
expected
follow-up commits must be reviewer-driven.
-->

## **Description**

<!--
Write a short description of the changes included in this pull request,
also include relevant motivation and context. Have in mind the following
questions:
1. What is the reason for the change?
2. What is the improvement/solution?
-->

Optimizes selected CI workflows by using Yarn cache support for the EAS
update dependency install and avoiding full-history checkouts where the
jobs do not need repository history.

This leaves history-sensitive workflows unchanged, including
feature-flag registry, merge-base, tag, branch-sync, and SonarCloud
paths.

Validation:

- Parsed the changed workflow YAML files locally.
- Ran the requested workflow grep for `fetch-depth: 0`,
`actions/setup-node`, `yarn install --immutable`, and selected git
commands.
- Ran `git diff --check`.
- Ran `actionlint` on changed workflows, with pre-existing
`actions/*@v3` and disabled-job warnings ignored.
- Ran a diff-scoped Codex Security scan: no findings.

## **Changelog**

<!--
If this PR is not End-User-Facing and should not show up in the
CHANGELOG, you can choose to either:
1. Write `CHANGELOG entry: null`
2. Label with `no-changelog`

If this PR is End-User-Facing, please write a short User-Facing
description in the past tense like:
`CHANGELOG entry: Added a new tab for users to see their NFTs`
`CHANGELOG entry: Fixed a bug that was causing some NFTs to flicker`

(This helps the Release Engineer do their job more quickly and
accurately)

## **Pre-merge author checklist**

<!--
Every checklist item must be consciously assessed before marking this PR
as
"Ready for review". A checked box means you deliberately considered that
responsibility, not that you literally performed every action listed.

Unchecked boxes are ambiguous: they are not an implicit "N/A" and they
are not
a silent "skip". See `docs/readme/ready-for-review.md` for the full
checklist
semantics.
