v0.1.3 — Remove psl dependency

🚀 v0.1.3 — Remove psl Dependency, Add Internal Public Suffix List

This release removes the dependency on the psl package and replaces it with an internal, CRAN-compliant solution using a locally cached copy of the Public Suffix List.

🔄 Changes

• ✅ Replaced psl::apex_domain() with an internal .get_registered_domain() helper.
• ✅ Added a data-raw/update_psl.R script to refresh the PSL during development.
• ✅ Stored psl_clean as internal data in sysdata.rda.
• ✅ Updated get_domain() to rely on the internal suffix logic.
• ✅ Added new unit tests for edge cases (e.g., wildcard and exception rules).
• ✅ Achieved 100% test coverage (covr::package_coverage()).
• ✅ Removed psl from DESCRIPTION and all related references.

📦 Package Check

• devtools::check() passes with 0 errors, 0 warnings, and 1 note (timestamp-related).
• Fully CRAN-compliant and ready for publishing.
