fix(dispatch_tree): use proper snake_case for dispatcher static names

Fix the static name generation for dispatch tree nodes to use a correct
snake_case conversion instead of a simple `.` to `_` replacement. Also
correct the `__comp` completion dispatcher name from triple underscore
to double underscore, resolving a mismatch between
`register_dispatcher!`
and `program_comp_gen`

+7. **\[macros:dispatch_tree\]** Fixed the static name generation for dispatch tree nodes to use `snake_case` conversion instead of simple `.` → `_` replacement, and fixed the `__comp` completion dispatcher static name from `__internal_dispatcher___comp` (triple underscore) to `__internal_dispatcher_comp` (double underscore), resolving a mismatch between the name generated by `register_dispatcher!` and the name used in `program_comp_gen`.

 #### Optimizations:
 
 1. **\[core:flag\]** Refactored the `special_argument!` and `special_arguments!` macros to replace index‑based `while` loops with iterator `position` and `drain`, improving both performance and readability.
