  1. fix(channel): refuse attachments that can't fit the chat's model, and… 

    … explain context overflows

A message whose attached files exceed the model's context failed its run and every later one,
since the transcript keeps it. ask and say now estimate attached files' tokens from their UTF-8
bytes and refuse a message over three quarters of the model's context window, naming the files
and the limit. A run that still overflows, such as one over a message stored by 0.0.48, ends with
an error that says to delete the message with the large attachment or pick a larger model.

Why: packages/channel/src/room.ts#function checkContext | estimate from UTF-8 bytes, not chars; pi-ai's chars/4 undercounts non-Latin text by ~2x, which is how multilingual PDFs overflowed
Why: packages/channel/src/channel.ts#function failed | overflow errors are explained in the projection, not stored, so replies already stored by older channels get the recovery hint too
