Fix button replay fingerprint matching

[0thernet]

Summary

• Match same-tag button fingerprints when both input types and nonempty text contents are present and equal.
• Preserve the existing accessible-name and structural-path matcher fallbacks.
• Add focused positive, negative, incomplete-identity, symmetry, and fallback-preservation tests.

Verification

• cargo fmt --all -- --check
• git diff --check
• Independent static/adversarial review: approved

Executable Rust validation is delegated to upstream CI. This change is intentionally separate from #289.

GitHub Actions marked this fork PR as action_required before creating any jobs. Could a maintainer approve the workflow run and review this focused matcher fix? The branch is current with main, formatting and diff checks pass, and the change preserves the existing accessible-name and structural-path fallbacks.

Updated this branch with a normal merge of current upstream main a19243969153027e9b1dce5fe47ca98abbd4ec46. New head: d0b8d6be4897bd5ae682b939ec2525e9388477b6.

The feature delta remains exactly the original 80-line change in lib/bombadil-schema/src/browser.rs; upstream's deprecated optional double-click delay is preserved. Independent review found no issues. Formatting, diff checks, and all three bombadil-schema unit tests passed on the updated tree.

The new exact-head CI run is waiting for maintainer approval before any jobs can run. No force-push or history rewrite was used.
