Greptile Summary

This PR makes Assembly extensions resolve to the canonical Assembly language. The main changes are:

• Custom language extension arrays now merge with base language data instead of replacing it.
• Extensions owned by a custom language are removed from other language entries before lookup maps are built.
• Assembly custom metadata now claims ambiguous .asm, .s, and .S extensions.
• Tests cover Assembly extension precedence and existing custom language entries.

Confidence Score: 5/5

Safe to merge with minimal risk.

The change is small, localized to language metadata loading, and includes tests for the updated Assembly extension behavior.

No files require special attention.

T-Rex Logs

What T-Rex did

• Observed the Rails test blocker log showing Bundler 2.3.15 cannot parse platforms: %i[ windows jruby ].
• Compared Language assembly: baseline before override log to Language assembly: post-change assertions log to review baseline behavior and post-change results.
• Validated the change using the Runtime validator harness (language_assembly_validation_harness.rb) as the generated narrow-proof validator.
• Confirmed that the after-change run produced exit code 0 and all assertions passed according to the post-change log evidence.

Important Files Changed

Filename	Overview
app/lib/language_utils.rb	Merges custom language arrays with base data and removes custom-owned extensions from other languages so extension lookup prioritizes canonical overrides.
config/languages_custom.yml	Adds Assembly extension overrides for ambiguous assembly suffixes so they are treated as canonical Assembly.
test/lib/language_utils_test.rb	Adds tests for Assembly extension precedence and existing custom language behavior.
