v0.4.0: Type Safety Modes — Two Axes of Type Control

11 commits | 45 files changed | +2,647 / -961 lines | 960 tests passing

Highlights

Two independent axes for type control:

• Runtime (NTNT_TYPE_MODE): strict (crash on mismatch) / warn (log + continue, default) / forgiving (silent)
• Lint (NTNT_LINT_MODE): default / warn (--warn-untyped) / strict (--strict)

World-class error messages — file:line, source snippets, expected/got context, fix hints:

error[E003]
  --> /path/to/file.tnt:3
  = Type error: Cannot apply '-' to String and Int
   |
   2 | let y = 42
   3 | let result = x - y
   |
  expected: compatible types for '-'
     found: String - Int

New type syntax:

• T? shorthand for Optional<T>
• Type aliases: type Handler = (Request) -> Response
• Array types: [Int], [String]
• Generics: fn identity<T>(x: T) -> T with full unification in the type checker

Bug fixes:

• Runtime errors now show accurate line numbers (was missing for all declaration-level errors)
• Parser EOF errors show correct line (was line 0)
• lib/route/middleware modules now have identical execution contexts (fixes stdlib imports in lib files)
• Lint correctly processes Located-wrapped declarations

Breaking changes

None. All new behavior is opt-in.
