silverwind 4f363d2748 ci: improve go caches (#38730)
Cache saves have been rejected since June because the repo sat above its
10 GB allowance, so every PR run fell back to a cache built with an
older toolchain and rebuilt the backend from scratch.

- go version in the `gobuild` and `golint` keys and `restore-keys`
- seeder triggers on `go.mod` and gained `workflow_dispatch`
- single writer for the `gomod` cache, the two were racing
- new daily `cache-prune` workflow holding the total under a limit
- `cache: false` for `setup-go` in release and cron workflows, it held
815 MB
- add `workflow_dispatch` so the cache workflows can be triggered
on-demand

name: go-caches
description: Restore the go module, build, and golangci-lint caches. Save only on the cache-seeder workflow.
# Only the cache-seeder workflow saves; rename requires updating cache-seeder.yml.
# The lint job restores but does not save the gobuild and gomod caches, so every key
# has a single writer and there is no contention on it.
# Seeder restores by exact key only (no restore-keys) so each go.sum seeds a clean
# cache and size stays bounded; do not add restore-keys here. PR runs keep them.
# The go version is part of the gobuild and golint keys because a toolchain bump
# invalidates every entry in them, so a cross-version fallback would restore
# gigabytes that no build can use. The module cache is version-independent.
