cue.prompts

Single source of truth for every Claude prompt in Cue.

Keeping them together (instead of scattered inline strings in digest.py / memory.py / suggest.py) makes it easy to diff prompt-only changes, to compare A/B variants, and to grep for the exact wording shipped in any given build. Structural formatting — timeline labels, bullet prefixes, JSON skeletons — stays in the calling modules; only the prose lives here.
