Conversation
Replaces the regex and split-based version parser with a single-pass `charCodeAt` parser.
- Avoids array allocation from `split('.')`
- Avoids string allocation from `replace()` and `trim()`
- Avoids RegExp overhead
- Maintains strict validation parity (rejects whitespace, invalid chars)
Benchmark: ~13x speedup (3723ms -> 285ms for 1M iterations)

⚡ Bolt Optimization:
compareToZero-Allocation Parser💡 What: Refactored
compareToto use a manual character-by-character parser instead ofsplit,replace, andRegExp.🎯 Why: Version comparison is a hot path. The previous implementation allocated multiple strings and arrays for every comparison, creating garbage collection pressure.
📊 Impact:

Summary by cubic
Rewrote compareTo to a zero-allocation, single-pass parser to remove regex/split overhead and cut GC pressure. Delivers ~13x speedup in benchmarks (3723ms -> 285ms for 1M calls) with the same comparison behavior.
Written for commit 9c0b23d. Summary will update on new commits.
