Greptile Summary

This PR auto-syncs two small documentation cleanups from the upstream cosmos/example repository into the docs site. The changes are purely cosmetic: a minor prose improvement in 01-prerequisites.mdx and a trailing-whitespace removal in 03-build-a-module.mdx.

• 01-prerequisites.mdx: Adds "on your machine" to the opening sentence for slightly clearer phrasing.
• 03-build-a-module.mdx: Removes a trailing space after a period on the intro paragraph — no content change.

All internal cross-links (02-quickstart, 04-counter-walkthrough, /sdk/next/learn/concepts/modules, etc.) resolve correctly to existing files. No logic, structure, or content issues were found.

Confidence Score: 5/5

Safe to merge — both changes are trivial documentation cleanups with no risk of regressions.

The entire diff consists of one wording improvement ("on your machine") and one trailing whitespace removal. All linked pages were verified to exist. No P0 or P1 issues found.

No files require special attention.
