chore: fix typos (#1820)

### Description

This PR corrects several minor typos in comments and documentation
across the codebase. The changes are non-functional and purely textual
to improve clarity and maintain a clean, professional codebase.

### Details

- Corrected misspellings:
  - `substract` → `subtract`
  - `specifed` → `specified`
  - `explicity` → `explicitly`

These fixes help enhance readability and eliminate minor distractions
during development and code reviews.

### Additional Info

No logic or functionality has been modified. All changes are restricted
to comments or non-executable doc annotations.
