Fix Linux daemon shell fallback before PTY spawn (#8237)

Browse Source

* fix: resolve daemon shell before spawning

* fix(daemon): reconcile shell-ready barrier with the resolved fallback shell

The adapter computes shellReadySupported from the preferred shell before
spawn. When the daemon falls back (e.g. to /bin/sh), the session would
queue startup commands for the full 15s ready-marker timeout and wrap
multiline prompts in bracketed-paste markers the fallback shell cannot
parse. Expose the spawned shell on SubprocessHandle and downgrade the
barrier and paste wrapping in TerminalHost when the actual shell cannot
emit the marker.

Also apply the Unix shell fallback after the relay env scrub so a
scrubbed SHELL cannot drop the corrected value, and cover the resolve-
before-launch-config ordering, the no-shell throw, and candidate dedup
with tests.
