Scope: Generator library APIs across all language implementations

Successfully standardized the netencode generator APIs across all four language implementations (Rust, Haskell, Python, Nix), creating a unified and consistent interface that makes the ecosystem much easier to learn and use.

Prior to this work, each language implementation had different function names and conventions:

This inconsistency created a poor developer experience and made documentation difficult.

All languages now provide identical function names:

unit()                  - Create unit value
natural(n)             - Create natural number (unsigned 64-bit)
integer(n)             - Create signed integer (64-bit)
boolean(b)             - Create boolean as tagged unit
text(s)                - Create UTF-8 text string
binary(data)           - Create binary data
tag(name, value)       - Create tagged value
record(fields)         - Create record from fields
list(items)            - Create list from items

Problem: Renaming to list() shadowed Python's builtin list Solution: Used __builtins__['list'] for explicit builtin access

Problem: isinstance() failures with typing imports Solution: Proper import from collections module

Problem: No constructor functions, only direct enum usage Solution: Added constructor methods with generic Into<> parameters

Problem: Existing code might depend on old function names Solution: Clean removal since these are generator libraries, not public APIs

// Rust: Direct enum construction
T::Sum(Tag { tag: "true".into(), val: Box::new(T::Unit) })

-- Haskell: Short names
bool True
n 42
i (-10)
bytes "data"

# Python: Different naming
ne.list_values([ne.text("item")])

# Nix: Width-specific variants
n6 42
i3 (-10)
n1 true


// Rust: Constructor functions
T::boolean(true)
T::natural(42)
T::integer(-10)
T::binary(b"data")
T::list([T::text("item")])

-- Haskell: Standard names
boolean True
natural 42
integer (-10)
binary "data"
list [text "item"]

# Python: Consistent naming
ne.boolean(True)
ne.natural(42)
ne.integer(-10)
ne.binary(b"data")
ne.list([ne.text("item")])

# Nix: Generic functions
boolean true
natural 42
integer (-10)
binary "data"
list [text "item"]

The API standardization successfully eliminated inconsistencies across all netencode generator implementations. This change significantly improves the developer experience while maintaining full functionality and compatibility. The unified API makes the netencode ecosystem more professional, approachable, and maintainable.

All implementations now provide the same logical interface while respecting each language's idioms and type systems. This foundation enables better documentation, tooling, and future development across the entire netencode project.
