"""The "About my library" note (Settings › AI assistant › About my library).

A short note the user writes once, which every AI request that writes or
changes library content reads: the chat, Draft with AI and the pack
builder. It holds what the model can't infer from one request: how the
library is named, which variables matter, the checkpoint family it is
written for, what the user never wants. Prior art: ChatGPT custom
instructions and Claude project instructions, where one stated rule beats
patterns the model has to guess (research note
`pr-drafts/next-feature-research-2026-10-22.md`, A6).

Kept short (`MAX_CHARS`) because small models lose the thread in a long
preamble. It goes at the end of the instructions, after the app's own rules,
so those still win where the two disagree. A chat keeps the note it started
with (`meta["note"]`), so editing it never re-reads an open chat's prompt.

`suggest_prompt` asks the model for a first draft from the library summary;
the user edits it before anything is saved.
