Subject: [PATCH] feat(parser): complete DotGet implementation with scope
 tracking
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Fixed tokenizer input.read() to use absolute positions
- Fixed FN_KEYWORD term ID (33 after DotGet added to expression)
- Added DotGet to expression for use as function argument
- All 8 DotGet tests passing
