`extras: $ => []` in the cart grammar made the parser fail at byte 0
on any whitespace-only or empty line before `pico-8 cartridge //...`.
Real PICO-8 carts always start with the header at byte 0 so this
rarely surfaced in production, but it ( a ) broke the `tree-sitter
test` corpus harness, which prepends a newline to each fixture, and
( b ) would mis-flag a hand-edited cart that gained an accidental
blank line up top.
Fix: prefix the `cartridge` rule with `repeat($._blank_line)` and add
a hidden `_blank_line` token matching `[ \t]*\n`. Junk content before
the header ( a non-blank, non-magic line ) still produces an ERROR.
Restores the test corpus that was dropped in v0.1 ( previously failing
on this same edge case ) and adds a fixture for the unknown_section
fallback while the corpus is being rebuilt.
