[Bug] Claude Code overestimates task duration and bails from tasks claiming they're too complicated

Bug Description

Claude Code has been consistently overestimating how long tasks will take in recent weeks. It will unprompted provide time estimates numbered in weeks for tasks that I know in the past would take it 30 minutes. This overestimate frequently leads to it bailing out early on tasks claiming that it can't complete them in one session.

Due to the timing of the regression coinciding with its new habit of offering to /schedule background agents as a "follow up" at totally inappropriate times, I suspect that the framing of the "offer to /schedule" prompt is skewing Claude towards the idea that it's always working on a weeks-long project, even in cases where it would be totally inappropriate for it to assume that.
