fix: preserve context across control boundaries

[smiggleworth]

Summary

• preserve component scope context across For, Show, and Case in DOM rendering, synchronous SSR, and hydration verification
• refresh existing For-owned item scopes transactionally when provider context changes while rendering empty-list fallbacks exactly once
• preserve nested provider precedence while rebasing reused vnode frames away from stale outer providers
• avoid traversing and stamping plain user objects in array-valued vnode props
• preserve every node in component-owned multi-node ranges during full parent reconciliation
• accept readonly arrays and readonly-array accessors in For
• compare context frames semantically so unrelated parent updates keep stable keyed rows stable
• bump @askrjs/askr to 0.0.75

This supplies the owning runtime fix for askrjs/askr-ui#14. The UI issue remains open until its downstream regression PR and package release complete.

Validation

• npm run check (35 repository checks, 151 unit tests, 1,257 jsdom tests, 40 browser tests, build and artifact validation)
• npm run bench:tier1
• packed patched core installed into askr-ui; focused ToggleGroup behavior passes

Regression coverage

• initial and updated provider context through For
• empty For fallback renders once per provider update and updates live DOM text
• initial provider context through Show and Case
• SSR and hydration verification through For, Show, and Case
• nested provider precedence inside For child scopes
• stale outer frame rebasing retains nested provider values
• stable keyed For rows do not rerender for unrelated parent state
• plain objects in array-valued component props remain unmodified
• component-owned multi-node ranges survive parent reconciliation
• direct and accessor readonly For sources, including frozen arrays
• keyed computed-array children remain supported

Pull request overview

This PR fixes context propagation across control-boundary primitives (For/Show/Case) so child scopes preserve the correct provider frame, including transactional refresh of stable keyed For rows when provider context changes. It also updates regression coverage and bumps the package version to 0.0.75.

Changes:

• Propagate and semantically compare context frames for control boundaries so stable keyed For rows stay stable on unrelated parent updates.
• Refresh For-owned child scopes transactionally when the provider context frame changes.
• Add jsdom regression tests covering For/Show/Case context preservation and stability; bump version + docs.
