Update release workflow

[wileyj]

Note: relies on composite PR stacks-network/actions#91 due to the changes in registry.

This change refactors the release workflow as follows:

• changes the binary build process from using docker to building on the VM directly
• docker images use the binary artifact archive, rather than assets from a published github release
• multiple approval gates are removed in favor of a single one to start the build
• docker images publish to ghcr (this will require some additional setup after merge)
• workflows and inputs have been simplified to reduce duplication and remove variables that aren't needed
• docker tags are simplified: stacks-blockchain is no longer tagged by default for ghcr
• workflow filenames have been renamed slightly to better reflect what they do. release-*.yml etc.
• building the ad-hoc docker image using the same artifact method, but is coped only for glibc x64/arm64
• all archives and images are attested, with the docker images also being signed with cosign (https://github.com/sigstore/cosign)
• dockerfiles used to create the images are re-organized based on target and purpose
• macos builds are building on macos runners, with the only cross-compiliation being for cpu/c stdlib, which only involves updating linkers and other build-time flags.
• removed the cleanup step when setting up docker. via composite recent runners don't benefit from this, and the storage is more than adequate now to build stacks-core.

Overall, the performance is much better than using docker - what was taking ~30 minutes (discounting timeouts and failures) is now reliably down to ~12 minutes per build (macos being the outlier, since it was tested on a 7GB machine with the release-lite profile).

a full test release workflow: https://github.com/wileyj/stacks-core/actions/runs/19481419227

and a specific run of just the release workflow to show the expected timing of the changes proposed here: https://github.com/wileyj/stacks-core/actions/runs/19475022815

and the ghcr images produced-
signer: https://github.com/wileyj/stacks-core/pkgs/container/stacks-signer/versions?filters%5Bversion_type%5D=tagged
stacks-core: https://github.com/wileyj/stacks-core/pkgs/container/stacks-core/versions?filters%5Bversion_type%5D=tagged

published test release: https://github.com/wileyj/stacks-core/releases/tag/4.0.0.0.6
published singer test release: https://github.com/wileyj/stacks-core/releases/tag/signer-4.0.0.0.6.0

finally - the builds are set to use the release profile, which willl require at least the macos-latest-large runner, with the linux runners currently set to use the default ubuntu-latest (this may be changed, but the timing on default runners was acceptable).

the binaries/images need more verification, but initial testing of produced artifacts looks good.

moving to ghcr - one thing i don't like is how all the layers (tagged or not) are visible on the packages page (see link above).
i have a feeling it's a UI diff compared to something like dockerhub, but it may be confusing for users looking for what is the latest tagged release.

a few things to follow up on:

• schedule a nightly build from develop. i think this should be easier than expected with the move to using artifacts built natively. a simple conditional tag if it's run via cron should be all that's needed (along with hardcoding to build nightly from develop, compared to any desired branch when run manually)
• github release is created in draft mode, but i think we could also pre-populate most of the release message from the changelog(s) using a tool like https://github.com/sean0x42/markdown-extract

there is also a question of if we should be re-running all the same tests (which should have been passing prior to release in order for the changes to merge), i.e. bitcoin tests.
on the other hand, there could be a case where a hotfix release breaks an existing test, and it woudn't be caught until the release ci.

update - one thing i notice that i'm not sure about (but shoudln't be a blocker to merge) is that the artifacts are being attested 2x for the same archive. this may be a result of the the archive name being identical for stacks-core and the stacks-signer release.

Edit: it is indeed because of the archive file naming being a duplicate for the release. so stacks-core & stacks-signer both having the same archive name like linux-glibc-x64.zip will produce 2 quite similar attestations, even though the context of that archive is different.
