v2.3.0

Fixed

• --mode runtime now addresses the player. It only ever affected cs exec;
  health and every canonical command went to the editor regardless. So
  cs health --mode runtime called a dead player healthy, and
  cs command session/list --mode runtime listed the editor's REPL sessions
  rather than the ones cs exec --mode runtime had created in the player.
  Commands whose contract does not require the editor now reach the player.
  command/list and command/registry.snapshot deliberately stay with the
  editor, which owns registry authority; answering them from a player would
  overwrite the project's cached contracts with its shorter list.
• When no player answers on 15500-15509, commands that need one exit 3 and say
  so instead of falling back to the editor.
• cs batch --mode runtime sent the whole batch to the editor while cs command
  reached the player, so the same command id answered from a different process
  depending on how it was invoked — and a batch of mutations applied to the
  editor. A batch is one roundtrip, so command/list and
  command/registry.snapshot cannot be split out of it and are refused there
  instead; request them separately without --mode runtime.

Added

• cs pull retrieves a file from whichever process is being addressed. A
  relative path resolves against the target's persistentDataPath — the form to
  use against another machine, since Android and iOS give a user no absolute
  path to hold. An absolute path names a file on the target and is used as
  given. Every pull reports which rule applied. Large files are fetched as
  successive ranges.
• references/player.md covers debugging a running player: what it answers,
  why a device reports no consoleLogPath, and how to record a profiler capture
  on a device and open it at home.
• runtime/info routing: the device, build, and well-known paths of whichever
  process replies.

Changed

• The runtime port probe runs its ten candidates concurrently at 1s each rather
  than one after another at 0.3s. Hosts that drop packets to closed ports made
  the sequential form cost the full timeout per port, and the longer per-port
  budget suits a player on another machine.
• The package-owned registry grows to 62 (56 authoring + 6 control).
