fix(ci): adapter npm publish must provide string spec

[Herklos]

Root cause

publish.yml ran this before adapter publish:

npm pkg set "dependencies.@drakkar.software/anchor=$VERSION"

npm pkg set treats . as nested keys. That wrote:

"dependencies": {
  "@drakkar": { "software/anchor": "3.4.0" }
}

instead of a string spec. npx npm@latest publish then failed with must provide string spec. Core only sets version, so it published. Adapters do not have a dependencies field; they already have peerDependencies["@drakkar.software/anchor"].

Failed run: https://github.com/Drakkar-Software/Anchor/actions/runs/35108337568 (v3.4.0).

Fix

• Set version from the tag only (same as core). Do not rewrite dependencies.
• Skip a version that is already on the registry so core 3.4.0 does not block adapters.
• workflow_dispatch so adapters can be published from main without moving v3.4.0.

After merge

Do not re-run the failed v3.4.0 jobs — they still use the old YAML from the tag. From main, run Actions → Publish TypeScript Packages → Run workflow. Core 3.4.0 will be skipped; both adapters should publish 3.4.0. No new tag required unless that dispatch is not used.

No npm publish from this PR.
