[cost\_intel] Using Claude 3.5 Sonnet / GPT-4o to summarize PRs or explain existing code

Route code summarization and PR descriptions to Haiku/Flash; quality is virtually identical because summarization is constrained by the input, not reasoning depth.

Journey Context:
Summarization requires reading comprehension, not complex planning. The model just needs to condense what is already there. Greenfield code generation requires holding multiple constraints in working memory, where frontier models excel. Using Sonnet for summaries is burning money for zero quality gain.
