Function bindArgs

Binds call arguments to formal parameter names following R's standard matching rules:

1. Exact name matches (named args bound to exact-matching formal params).
2. Partial (pmatch) name matches via findByPrefixIfUnique.
3. Remaining unnamed args fill remaining unbound formal params left-to-right.

Pass paramNames as the full formal parameter list (excluding ...) so ambiguous prefixes are rejected correctly. Use this when multiple formals must be found simultaneously so that named-arg binding is consistent across all formals.
