chore(docs): fix vale lint errors

Replaces 'e.g.' with 'for example' in doc comments (Google.Latin),
swaps an em dash for a semicolon in a runtime-field docstring
(Google.EmDash), and adds 'launchd' to the technical vocabulary.

Also drops docs/superpowers/plans/2026-05-21-macos-native-integration-tests.md;
the plan was a one-time implementation artifact and the PR description
on #1735 supersedes it.
