GRPM 0.8.3 — SRC_URI Evaluation Hotfix

Critical fix for packages with dynamic SRC_URI generation (#50).

Summary

Fixes grpm fetch for packages like gcc that use eclasses to dynamically generate SRC_URI. Previously, version extraction was broken causing incorrect distfile URLs.

What's Fixed

• gcc distfile selection — grpm fetch =sys-devel/gcc-13.4.1_p20250807 now downloads correct files
• SRC_URI evaluation — Pure Go evaluation using mvdan.cc/sh interpreter with full eclass support
• ver_cut function — PMS-compliant version extraction (e.g., gcc-13-20250807 instead of broken gcc-13.4.1_p20250807-20250807)
• Eclass caching — Efficient eclass loading with inheritance tracking

Technical Notes

The ver_cut implementation uses indexed variables instead of bash array slicing due to a bug in mvdan.cc/sh where ${arr[@]:start:len} doesn't work correctly in command substitution. This workaround ensures correct version extraction for toolchain.eclass and similar complex eclasses.
