Sync parser_test.zig test section with upstream, adding ~40 new tests (testError, testCanonical, testTransform). Remove extra blank lines between tests to match upstream formatting. Fix tokenizer keyword lookup bug: getKeyword() returned TOKEN_INVALID when input was longer than a keyword prefix (e.g., "orelse" matched "or" prefix then bailed out instead of continuing to find "orelse"). Fix parser to handle if/for/while expressions in type position (e.g., function return types like `fn foo() if (cond) i32 else void`). Add labeled block support in parsePrimaryTypeExpr. Replace assert for chained comparison operators with longjmp error. 365/381 tests pass. Remaining 16 failures are parser limitations for specific syntax patterns and error recovery.

zig0 aspires to be an interpreter of zig 0.15.1 written in C.
Testing
Quick test:
zig build fmt && zig build
Debugging tips
Test runs infinitely? Build the test program executable:
$ zig build test -Dno-exec
And then run it, capturing the stack trace:
gdb -batch
-ex "python import threading; threading.Timer(1.0, lambda: gdb.post_event(lambda: gdb.execute('interrupt'))).start()"
-ex run
-ex "bt full"
-ex quit
zig-out/bin/test
You are welcome to replace -ex "bt full" with anything other of interest.
