Bug Fixes

• jetsocat: validate JMUX listener destination at CLI parse time (#1823) (eeb90df5a6)

  Previously, a tcp-listen://<addr>/<destination> argument without a
  port (e.g. a missing :22) was accepted at startup, but every incoming
  connection was then silently dropped with only a debug-level log. The
  tunnel appeared to work yet forwarded nothing.

  The listener destination is now parsed during CLI argument parsing, so a
  malformed destination fails immediately and visibly with a clear error,
  before any listener is bound.

• dgw: improve session-level tracing (#1822) (304ecf078a)

• dgw: TRP live-shadow sizing + large-line panic (#1816) (9a0c1e6304)

  Fixes two TRP-only issues in the terminal "live-shadow" streaming path by correcting terminal sizing metadata in emitted asciicast JSON and preventing panics when decoded lines exceed the caller's read buffer.

• agent-installer: pin Newtonsoft ToString overload to avoid GAC binding crash (#1833) (cd66dd1abd) (DGW-396)

  Fixes a failure where installing or reconfiguring the Devolutions Agent
  could roll back with a MissingMethodException on machines that already
  have an older Newtonsoft.Json in the Global Assembly Cache (GAC).

• agent: harden PSU Event Hub worker lifecycle (#1830) (1827007dd2)

  Hardens the experimental PowerShell Universal Event Hub compatibility
  path so agent deployments are less likely to exhaust local PowerShell
  workers, leak completed results, or keep stuck scripts running
  indefinitely.

• webapp: pin asciinema-player to 3.8.2 (#1820) (b12e2adfab) (DGW-394)

  asciinema-player 3.9.0 reworked its WebSocket driver to use subprotocol
  negotiation, which the gateway terminal-stream WebSocket does not
  perform. As a result live terminal playback broke and showed "Stream
  ended". Pinning to 3.8.2 restores live terminal playback.
