Reduces the CI cache growth and disk pressure behind the flaky `No space
left on device` failures in
https://github.com/go-gitea/gitea/issues/37974.
**`go-cache`** — the cache-seeder saved with a `restore-keys` prefix
fallback, so every `go.sum` change restored the previous cache and
re-saved the union; old module versions and stale build objects
accumulated (~3 GB → ~7 GB) and overflowed disk on smaller runners. Drop
`restore-keys` from the seeder **save** branches so each `go.sum` seeds
a clean, size-bounded cache. PR runs keep `restore-keys` for warm-start
fallback.
**`free-disk-space`** — delete the unused preinstalled toolchains in
parallel (~86 s → ~54 s) and log `df -h /` before/after.
Measured during review: the hosted `ubuntu-latest` fleet is
heterogeneous — most runners have ~89 GB free on `/` (a full pgsql
integration shard peaks at ~17 GB used), but a minority arrive nearly
full and fail mid cache-restore. The toolchain deletion is the headroom
that keeps those runners green, so it stays; the cache bound shrinks the
footprint for every runner.

Reduces CI minutes consumption by narrowing the `files-changed` filters.
- DB matrix (`pgsql`/`mysql`/`mssql`/`unit`) now runs only on real
backend changes. `test-sqlite` stays gated on `actions`, so it remains
the smoke check that validates CI-infra changes (composite-action edits,
workflow edits, renovate action-pin bumps) without spinning up the full
matrix.
- Fix the `templates` filter: the SVG template linter is
`tools/lint-templates-svg.ts`, so the `tools/lint-templates-*.js` glob
matched nothing.
- Add missed paths: `tsconfig.json` and
`tools/generate-svg-vscode-extensions.json` to `frontend`,
`eslint.json.config.ts` to `json`, and
`.github/actions/docker-dryrun/**` to `docker`.
