Add an opt-in CODEOWNERS check that flags slashless directory rules in reports and CI.
This lets teams enforce a clearer directory style without changing default matching behavior.

Made-with: Cursor

Preserve pattern-only CODEOWNERS lines so the last matching rule can
clear inherited ownership like GitHub documents.

Add parser and CLI coverage for ownerless overrides and clarify the
README wording around last-match precedence.

Made-with: Cursor

Add an opt-in GitHub owner validation mode so invalid owners no longer count toward
coverage in parity checks.

Gracefully fall back when GitHub cannot conclusively expose repo access details,
including team visibility edge cases, and warn instead of misclassifying owners.

Made-with: Cursor

GitHub ignores escaped leading # patterns and bracket expressions, so treating
them as valid rules can mark files owned when they are actually uncovered.

Skip those rules during parsing, add parser and CLI regressions, and document
the stricter parity behavior.

Made-with: Cursor

Preserve raw CODEOWNERS patterns until regex compilation so escaped * and ?
stay literal instead of expanding to wildcards during ownership matching.

Add parser and CLI regressions to protect GitHub parity for literal-character
filenames without regressing escaped spaces.

Made-with: Cursor

GitHub ignores active CODEOWNERS files larger than 3 MB, which can make audits
report ownership that GitHub would skip. Surface the warning in report output and
add a dedicated fail flag so CI can enforce the parity check directly.

Made-with: Cursor

Align the ownership explorer with CODEOWNERS coverage by including email owners in the
report index and HTML UI. Rename the report schema to generic owner terminology and add
CLI regression coverage for email-owner parity.

Made-with: Cursor

Improve the npm-facing README so the core value, quick start, and option groups are
clearer to scan. Reformat the CLI help output into spaced sections and make the
help-output test resilient to future column-width tweaks.

Only conventional commits that touched publishable CLI/runtime files are included in this release.
