v0.0.11rc2 (pre-release)

Pre-release — try it with pip install --pre -U retalk (a plain pip install retalk keeps giving 0.0.10).

Changes since 0.0.11rc1:

• Removed retalk auth (it only ever existed in rc1). A child process can't set its parent shell's environment, so auth needed an eval wrapper — and every eval-free alternative trades real complexity or safety for a few keystrokes. The documented way is the plain, standard one:

  export RETALK_USER=alice
  export RETALK_PASSPHRASE="<YOUR-PASSPHRASE>"

• README: placeholder shortened to "<YOUR-PASSPHRASE>"; --peer values consistently quoted (--peer "bob").

Everything else from rc1 is unchanged: retalk show USER PEER chat view (--follow for live), --save rename, zsh-paste-safe CLI output, quoted placeholders, post-verify next-steps block. 49 tests pass.
