fix clippy, cspell, and comparison TypeError message format
- Collapse nested if-let chains in pointer.rs (clippy::collapsible_if) - Move spell-checker disable comments to cover actual string constants - Use "GCC System V" instead of "gcc-sysv" in comment - Use CPython-compatible comparison TypeError message: "'<' not supported between instances of 'X' and 'Y'" instead of "unsupported operand type(s) for <: 'X' and 'Y'"
