Port tests from upstream parser_test.zig:
- "respect line breaks before functions"
- "simple top level comptime block"
- "two spaced line comments before decl"
- "respect line breaks after var declarations"
Implement in parser.c:
- parseSuffixOp: array access (a[i]), field access (a.b),
deref (a.*), unwrap optional (a.?)
- Multiline string literal parsing
- Slice types ([]T, [:s]T) and array types ([N]T, [N:s]T)
- Fix comptime block main_token in parseContainerMembers
Fix zigData mapping in parser_test.zig:
- field_access, unwrap_optional use node_and_token (not node_and_node)

Port "zig fmt: respect line breaks in struct field value declaration"
test from upstream parser_test.zig.
Implement in parser.c:
- Slice types ([]T, [:s]T) in parseTypeExpr
- Array types ([N]T, [N:s]T) in parseTypeExpr
- Multiline string literals in parsePrimaryTypeExpr
- Add comments explaining why const/volatile/allowzero pointer
modifiers are consumed (not stored in AST; renderer re-derives
them from token positions)
