feat(cli): 1.32.0 — multi-session UX bundle (self-identity, --self fan-out, broker welcome)

Nine UX bugs surfaced from a real two-session interconnect smoke
test, shipped together.

Self-identity is visible
- peer list now shows the caller as (this session), sorted to top.
  Daemon path resolves session pubkey via /v1/sessions/me so
  isThisSession is set correctly warm.
- whoami shows session pubkey, session id, mesh, role, groups, cwd,
  pid when run inside a launched session.

Sibling-session disambiguation
- peer list rows carry sid:<short> tag so visually-identical rows
  can be told apart at a glance.

Daemon hidden by default
- claudemesh-daemon presence rows hidden from peer list by default.
  --all opts back in. Header shows N daemon hidden when applicable.

--self flag works end-to-end
- Argv parser was greedy: --self ate the next arg as its value.
  BOOLEAN_FLAGS set in cli/argv.ts now lists known no-value switches.
- message send subcommand now passes self through (only legacy send
  was wired before).
- Help text lists --self.

Member-pubkey fan-out
- Sending to your own member pubkey with --self now resolves to every
  connected sibling session and sends one message per recipient.
  Required because the broker drain matches target_spec only against
  full session pubkeys; member-pubkey sends queued but never drained.

Broker welcome at launch
- After the launch banner, one line confirms WS state, peer count,
  and unread inbox count. Best-effort — falls back gracefully.
