Plumb cwd through the web-shell terraform module

Add a `cwd` input to terraform/web-shell/ that propagates to run.sh as
WEB_SHELL_CWD so web-shell sessions open in the working directory Coder
already collects via coder_parameter.directory, and wire the module into
the root workspace template alongside code-server / jetbrains.
