fix(web): compact recent path labels

[techotaku39]

Summary

• Show only the final two path segments for recent-directory buttons in the New Session form.
• Preserve the full path in the button title and when selecting a recent path.
• Reuse the same cross-platform formatter in the New Session form and session list.
• Add POSIX and Windows path formatting plus click-preservation regression coverage.

Validation

• bun run --cwd web test src/utils/path.test.ts src/components/NewSession/DirectorySection.test.tsx src/components/SessionList.test.ts — 55 tests passed.
• bun typecheck — passed.
• pwsh -NoProfile -File scripts/Invoke-HapiTaskPlaywright.ps1 -Name investigate-recent-path-display -Suite Root terminal-wrap-fidelity.spec.ts — 2 tests passed.
• Manual smoke test on the Full test environment — the New Session page displayed Agent/Hapi, retained the full path in the button title, and restored the full path to the directory input after clicking.
• bun run build — passed.

[MINOR] Keep the full path as the accessible name

The compact text becomes the button's accessible name; title is only a fallback when the element has no other name. As a result, paths such as /work/client/Agent/Hapi and /archive/Agent/Hapi are both announced as Agent/Hapi, so assistive-technology users cannot tell which directory will be selected. Keep the compact visible text, but expose the full path semantically and update the role query in the regression test.

Suggested fix:

<button
    // ...
    title={path}
    aria-label={path}
>
    {getPathDisplayName(path)}
</button>

Summary

• Review mode: follow-up after new commits
• No correctness, security, regression, data-loss, performance, or maintainability issues found in the latest modified lines. The new commit resolves the prior accessible-name finding by preserving the full path in aria-label; the complete latest diff was re-reviewed. Residual risk: GitHub test and integration checks were still pending at review time.

Testing

• Not run (automation); PR code was not executed. Added tests cover POSIX and Windows compact formatting plus full-path click/accessibility preservation. GitHub test and integration checks pending.
