Closes github/primer#6402

Typing in a nested TreeView control can crash typeahead or steal focus. Restrict typeahead to keystrokes originating on tree items so nested controls retain their keyboard behavior without changing the public API or normal tree-item searches.

Changelog

Changed

• TreeView ignores nested-control keystrokes before updating its typeahead search buffer.

Rollout strategy

• No changes needed in github/github-ui
• Needs changes in github/github-ui
• Ships with feature flag(s)
• Not sure
• None

Testing & Reviewing

Click a reorder button in the TreeView Leading Action story, then type zz quickly. This should no longer produce the matching stack: getAccessibleName → useTypeahead → onKeyDown. If you do this against the prod storybook you'll see the original error we're fixing here.
