* chore(ui): migrate vite 6 -> 8 and plugin-react 4 -> 6
Supersedes the auto-generated bump in #2496, which only updated vite and
left @vitejs/plugin-react on a peer range that excludes vite 8, breaking
the UI build (and every Go job that embeds the UI assets) with ERESOLVE.
- vite ^6.0.0 -> ^8.0.13
- @vitejs/plugin-react ^4.3.0 -> ^6.0.2 (peers vite ^8.0.0 only)
- vite-plugin-singlefile ^2.0.0 -> ^2.3.3 (peers already allowed v8)
- engines.node >=20 -> ^20.19.0 || >=22.12.0 (Vite 7+ requirement)
Vite 8 ships Rolldown instead of Rollup, which rejects bundle mutation in
generateBundle. The rename-output plugin was doing exactly that to flatten
the singlefile-inlined HTML from src/apps/<app>/index.html down to
<app>.html. Refactored it to hoist the file in closeBundle (post-write)
and renamed it to flatten-output to reflect what it actually does.

* chore(ui): give flatten-output a clearer error when the HTML is missing
Addresses Copilot review feedback on #2501: if the singlefile-inlined HTML
isn't where we expect it (e.g. because a future Vite/Rolldown change alters
the output path), throw with the app name and expected path instead of
letting renameSync surface a bare ENOENT.

* perf(ui+ci): cache build artifacts and run vite in single process
Introduce a content-addressable cache for the embedded UI HTML and refactor
the build script to invoke vite once per Node process instead of three
times.
* New ui/scripts/build.mjs runs vite build() in a loop within one process,
removing the cross-env dev dependency and avoiding redundant plugin/JIT
warm-up. Local build time drops from ~2.4s to ~1.5s.
* New .github/actions/build-ui composite action restores
pkg/github/ui_dist/{get-me,issue-write,pr-write}.html from cache keyed on
hashes of ui/ sources and the lockfile. On cache hit it skips Node setup
and the build entirely; on miss it sets up Node and runs script/build-ui
as before. Saves ~6s per workflow on Go-only PRs, which is the common
case across seven workflows.
* Replace the duplicated setup-node + Build UI pair in seven workflows
(go, lint, docs-check, license-check, goreleaser, mcp-diff, code-scanning)
with a single uses: ./.github/actions/build-ui line. code-scanning keeps
a dedicated setup-node for the JavaScript CodeQL path.
Output files are byte-identical to the pre-refactor build.

* perf(ci): share UI artifact cache across runner OSes
The cached HTML output is platform-independent, so set
enableCrossOsArchive on the cache step. With this any OS can restore
the cache populated by any other OS — one shared cache instead of three.
