EXT-26: append an OS + shell-dialect note to the composed code-mode system prompt.
The model was never told its host OS or which shell run_shell_command uses, so on
non-POSIX hosts it defaulted to POSIX idioms that fail (ran ls where cmd.exe has dir, a
multi-line echo-redirect that wrote 0 bytes, a PowerShell here-string, python -c multi-line).
This is ORTHOGONAL to the EXT-13/16/22 path-namespace notes: those say WHERE the model is (path
form); this says WHAT shell it speaks (dialect). Backend-agnostic — the lean backend also exposes
run_shell_command, so GS2-27 composes it in the shared path.
The shell is derived from the SAME rule Node’s spawn(command, { shell: true }) uses — exactly
how run_shell_command spawns (GthDevToolkit spawn) — so on win32 it is cmd.exe (via
%ComSpec%) and on POSIX it is /bin/sh (POSIX sh, NOT guaranteed bash). Computed from
process.platform at call time so the text is correct per host. Returns the note alone when
there is no base prompt. A single injection is authoritative (nothing in the base prompt
contradicts shell dialect), so unlike EXT-22 no correction middleware is needed.
