Previously, _wrap_command() wrote pwd to a file on the remote (container,
sandbox, SSH host), then _update_cwd_from_file() read it back via another
_run_bash() call. On Modal/Daytona this was a full API round-trip just to
read 20 bytes.
Now the wrapping template echoes the cwd to stdout with markers:
printf '\n__HERMES_CWD__%s__HERMES_CWD__\n' "$(pwd -P)"
_extract_cwd_from_output() parses it from the output already in memory.
Zero extra round-trips on any backend. The cwdfile, _read_file_in_env(),
and per-backend overrides are all deleted.
