fix(parser): infinite loop on newlines in multi-import, multi-line params, type args, struct patterns

Parser would hang (infinite loop) when encountering newline tokens
inside certain constructs because expect() returns without advancing
position when the expected token doesn't match.

Fixed 5 places in parseBaseType, parsePrimaryPattern, parseTypeParams,
parseParamList, and parseUseDecl by adding newline-skipping at the
start of each iteration.

Verified: compiler no longer hangs/crashes on all 3 real-world apps
from apps/ (boko-framework, jwt-pitbul, nexus).

 Bux is a fast, compiled, strongly-typed systems programming language. Features a C backend for native code generation, raw multi-line strings, gradual ownership (opt-in borrow checking), async/await, generics, algebraic enums, and a package manager.

+## Applications
+
+The `apps/` directory contains real-world Bux applications that serve as integration tests for the compiler:
+
+| App | Description | Lines |
+|-----|-------------|-------|
+| **boko-framework** | Async web framework (like FastAPI), multi-threaded HTTP server | ~660 |
+| **jwt-pitbul** | JWT CLI tool — sign, verify, decode (HS256/384/512, RS256/384/512, ES256/384, EdDSA) | ~326 |
+| **nexus** | High-performance HTTP/1.1, HTTP/2 & WebSocket server | ~550 |
+
+The bootstrap compiler successfully parses and type-checks all three applications without hanging or crashing.
