chore: clarify rule about trailing periods

[mateo-berri]

I notice Claude applies the rule irregularly. This aims to fix that

Greptile Summary

This PR tightens the no-trailing-period writing guideline in CLAUDE.md so the intent is unambiguous: the rule applies to every paragraph, not only the final one in a document or comment.

• The single changed line in CLAUDE.md appends two clarifying sentences to the existing bullet, spelling out scope ("every paragraph, not just the last one") and offering a rule of thumb ("unless there's a sentence immediately after, don't add a .").
• The wording of the new sentences is internally consistent — mid-bullet sentences that are followed by another sentence do use a period, while the final sentence ends with a closing quotation mark, so the rule applies to itself correctly.

Confidence Score: 5/5

Only CLAUDE.md is touched; no production code, tests, or configuration files are affected.

A single-line clarification to a style guide with no code changes, no risk of behavioral regression, and the expanded wording correctly follows its own rule.

No files require special attention.

Important Files Changed
