Switch to new enums instead of alias

[Pollux12]

Greptile Summary

The PR replaces alias-based annotations for global enumerations with flat numeric enum declarations so completion can suggest global constant names.

• Emits ---@enum NAME : number and lists each numeric member by its global identifier.
• Includes available member descriptions while omitting descriptions that are empty.
• Updates writer tests to assert the new enum representation and continued exclusion of nonnumeric TODO values.

Confidence Score: 5/5

The PR appears safe to merge, with no concrete changed-code failure identified.

The implementation and tests consistently switch global enum output from numeric aliases to named flat enums while preserving the existing numeric-member filtering and an explicit numeric base.
