🔖 Bump workspace packages to 0.8.0

[taras]

Why

The rolling draft contains multiple breaking changes, including the namespaced Markdown props contract from #372, while every publishable manifest still declares the already-released 0.7.0. The next release therefore needs a minor version bump to 0.8.0 before the draft can be published.

What changes

Before:

• Publishable @executablemd/* manifests declared 0.7.0.
• The corresponding workspace entries in bun.lock declared 0.7.0.
• The draft-release guard warned that the manifest version was already released.

After:

• All ten publishable workspace packages declare 0.8.0 in both deno.json and package.json.
• Their ten bun.lock workspace entries declare 0.8.0.
• The private @executablemd/test-support package remains at 0.0.0.

How to verify it

• deno task lint — passes.
• deno task check — passes.
• deno task check:jsr — passes with Success Dry run complete for 0.8.0.
• deno task test scripts/tests/bump-version.test.ts — passes, 5/5 steps.
• git diff --check — passes.
• The final diff contains only the 20 publishable manifests and their workspace versions in bun.lock.

Scope

Included

• Lockstep package manifest bump from 0.7.0 to 0.8.0.
• Matching workspace-version restamp in bun.lock.

Intentionally unchanged

• Package dependencies and lockfile resolutions.
• The private @executablemd/test-support version.
• Source code, specifications, and release workflows.
• Publishing the draft release; that remains a separate maintainer action after this PR merges.

New dependencies

None.

Generated or mechanical changes

• deno task bump 0.8.0 stamps the publishable manifests.
• bun.lock is mechanically restamped as required by the release-process specification.

Risks and limitations

• Merging this PR prepares the repository and rolling draft for v0.8.0; it does not publish or tag the release.
• Recovery or rollback: revert this version-only commit before publishing if the release is deferred.

Scope confirmation

• Every changed file supports the purpose described above.
• Unrelated cleanup and formatting changes are excluded.
• Generated or mechanical changes are clearly identified.
• The description matches the final diff and test results.
