### Release 1.2.4 — Full TOML Support

This release completes **TOML configuration support**, bringing it to full parity with YAML and JSON.

**Highlights**

* TOML configs now support imports, profile overlays, and environment variable expansion
* Import resolution correctly handles format aliases (e.g. `.yaml` / `.yml`)
* Loader logic hardened around format vs extension semantics
* Comprehensive tests added to validate TOML behavior and parity

**Compatibility**

* Fully backward compatible
* No API or configuration changes required

This is a **patch release** that completes existing functionality without altering behavior for current users.
