ci(solid-adapter): add release-solid.yml + document adapter releases

[avanelsas]

Summary

Completes the release infrastructure for the five framework adapters.

What's published vs not (from investigation)

Package	npm version	Workflow file
@vanelsas/baredom	3.2.0 (published)	release.yml
@vanelsas/baredom-react	2.1.0 (published)	release-react.yml
@vanelsas/baredom-angular	2.7.0 (published)	release-angular.yml
@vanelsas/baredom-vue	not published	release-vue.yml (ready, awaiting tag)
@vanelsas/baredom-svelte	not published	release-svelte.yml (ready, awaiting tag)
@vanelsas/baredom-solid	not published	missing — added in this PR

Changes

1. New .github/workflows/release-solid.yml — mirrors release-vue.yml (Solid uses plain tsc, same build shape as Vue). Triggers on solid-v* tags. Regenerates adapter sources, fails on git-diff drift, builds with tsc, publishes @vanelsas/baredom-solid to npm with --access public, and creates a GitHub Release.

2. Extended docs/RELEASING.md from core-library-only (17 lines) to cover the adapter release process. Adds:

   • Per-adapter workflow table with tag patterns
   • 3-step adapter release procedure
   • First-time-publish NPM_TOKEN permission section explaining Automation vs Granular tokens and the 403 / EOTP failure modes

Pre-flight verification (locally)

• bb scripts/generate_solid.bb → 104 wrappers generated
• git diff --exit-code adapters/solid/ → clean (workflow's drift guard will pass)
• cd adapters/solid && npx tsc → exit 0

After this PR merges

Adapter publishes will be:

git tag svelte-v0.1.0 && git push origin svelte-v0.1.0   # canary first
git tag solid-v0.1.0  && git push origin solid-v0.1.0
git tag vue-v0.1.0    && git push origin vue-v0.1.0

First-publish caveat: confirm NPM_TOKEN permission for the new package names before tagging. If it's a Granular token with a fixed allowlist, the new names need adding on npmjs.com (or grant scope-level write on @vanelsas). See the new RELEASING.md section.

Test plan

• bb scripts/generate_solid.bb produces output identical to what's committed
• git diff --exit-code adapters/solid/ clean — workflow's drift guard will pass
• cd adapters/solid && npx tsc exits 0 — workflow's build step will pass
• Workflow file structure matches release-vue.yml (Solid is the closest analog — both use plain tsc)
• Live verification (post-merge, follow-up): push svelte-v0.1.0 as canary, confirm npm publish succeeds, then push solid and vue tags
