v0.95.0

Added

• The cockpit reads the raw event tail in two requests on any log size
  and states why a causality trace is empty, riding the since=latest
  shortcut and the absence notes below.
• The hub now remembers directed chats that reached no live connection:
  a bounded per-target ledger (biggest blackhole first, stalest target
  evicted beyond 200, cleared the moment the addressed name connects)
  rides the state snapshot as dead_letters, so the dashboard and the
  cockpit can show "N messages, nobody listening" instead of leaving
  the blackhole invisible. Honest scope: an entry attests only that no
  live connection matched at send time — feed-history draining remains
  the doctor's addressee check.
• Directed-message blackholes are now visible and drainable. syn inbox --as NAME (repeatable; standing set via the comma-separated
  $SYN_ALIASES) drains additional identities — a role name like
  project/coordinator alongside the resolved one — each under its own
  cursor, so no reader ever consumes another's delta. And synapse doctor gained an addressee check: recent directed traffic whose
  target has no inbox cursor, no live waiter, and no live connection is
  reported with message counts and the drain command, because a message
  nobody reads otherwise waits for a human to relay it — the exact
  failure the bus exists to remove.
• /events.json accepts since=latest — the tail shortcut that starts
  at the log's end instead of walking a large history to catch up.
• A present: false causality-feed answer now carries a note naming
  which absence it is: an event recorded but outside the coordination
  causal graph (chatter carries no causal edges), or no event at that
  sequence at all.
