⚙️ [Maintenance]: Add afterall to codespell ignore words list (#17)

Adds `afterall` to the codespell ignore words list in `.codespellrc` to
prevent false positive spell check warnings in CI linting. This term is
commonly used in PowerShell (e.g., Pester's `AfterAll` block) and should
not be flagged as a misspelling.

## Codespell configuration

The `.codespellrc` linter configuration now includes `ignore-words-list
= afterall`, which tells codespell to skip this word during spell
checking. No changes to functionality or shipped artifacts.
