say "bytes", not "characters", where the limit is bytes

Browse source 
`check()` enforces the entry limit on `len(text.encode())`, but every place
that asks the agent for a line calls it characters:

  - the `nap` compression prompt ("at most %d characters")
  - `note`'s usage line ("at most %d chars")
  - the installed prompt in TEMPLATE ("max {chars} chars")

An agent budgeting characters overshoots on any non-ASCII text and only
finds out from the error, one round trip per attempt. The error message
already explains the byte cost -- this just says it up front, at no cost
to the prompt.

Five words, no behaviour change. 109099 tests pass.
