fix: agent prompts say trust the story description instead of always investigating

Agents were spending entire $5 budgets grepping the codebase and reading
git history instead of making fixes when the story already specifies
exact file paths and function names. Changed bug workflow from
"investigate root cause first" to "trust the story, act fast" — go
directly to the specified location when the story tells you where.
