rebrand to notevi: one CLI over the jj sidecar

vr and vrsite become a single binary. vrsite/ folds into a web package in
one module (0x4200.cafe/notevi); "notevi web" serves and exports exactly
what vrsite did, and "notevi read/grep/note/query" is unchanged.

The sidecar is renamed with it: notevi_log, notevi-log.jsonl, and the
description "private: notevi log". The pre-rebrand names are still
recognized, so an old repository opens and reads; it is renamed in place
on the first write, or up front with "notevi migrate DIR...".

That rename cannot be a single mv inside jj run. jj only auto-tracks a
*new* file in the run working copy below a size limit it does not take
from the command line, so writing a whole log under a name the change has
never held is silently dropped while jj reports success. ensureLogFile
creates the file empty first and lets every later byte be a modification
of a tracked file, which snapshots at any size; that also fixes the same
latent bug when importing a large legacy vr-log.jsonl.

Adds a bem-te-vi mark (favicon and nav brand) and a README.
