bug(react): source hooks freeze initial configuration options #391

Summary

The audit performed while fixing #373 found the same initial-render option capture pattern in additional React source hooks. Several source factories are memoized for the component lifetime while closing over source options from the first render.

Concrete examples:

• useAskableDOMSource: target selection (ref/selector), includeAttributes, includeHTML, maxTextLength, describe, and kind
• useAskableScrollSource: target selection (ref/selector/getElement), getActiveSection, describe, and kind
• state-backed source hooks commonly keep snapshot data current through refs but can still freeze configuration such as describe, kind, caps, filters, and source-specific options

This is separate from the navigation-specific fix in #373 and should be handled systematically rather than expanding that PR.

Expected behavior

Source hook options should reflect the latest committed React render without:

• re-registering the source
• exposing callbacks from abandoned concurrent renders
• resetting source-owned state/history unnecessarily
• silently freezing scalar or callback options from mount

Acceptance criteria

• Audit every React useAskable*Source factory with an empty or intentionally narrow memo dependency list
• Add rerender regressions for each confirmed stale option class
• Add a suspended/abandoned-render regression for any shared latest-value helper
• Keep registrations stable across option changes
• Preserve source-owned state when options change
• Verify SSR behavior and the full React/workspace suites
