Summary

• Recognize case-insensitive file:// URI schemes when resolving relative file links in Todo documents.
• Add a regression for mixed-case links and record the user-visible fix in the changelog.

Verification

• Regression failed on unchanged implementation (no links returned), then passed after the fix.
• npm run check — passed: typecheck, 428 tests, webpack compile, and format check.
• git diff --check upstream/develop...HEAD — passed.

Risk

• Low: changes only the relative-link matching scheme flag; existing path handling is unchanged.

Reviewed the scheme-matching change and relative-link resolution. Adding the case-insensitive regex flag correctly recognizes FILE:// and File:// without altering filename casing, URI decoding, document-relative path resolution, or punctuation/range handling. The regression checks both matched ranges and resolved target paths.

Updated this branch with the already-reviewed Markdown and estimate changes and preserved each changelog entry. Validation passed on the combined head: typecheck, all 437 tests, webpack development build, format check, and git diff whitespace check. No functional corrections were needed in this PR.
