fix(integrations): agy honors SPECKIT_INTEGRATION_AGY_EXTRA_ARGS (#3347)

AgyIntegration.build_exec_args returned [exe, '--print', prompt] without
calling _apply_extra_args_env_var(), so the documented per-integration
extra-args env hook was silently dropped for agy — same class as the
cursor-agent fix #3265. Append the hook after the positional prompt,
matching the devin integration's shape. agy still ignores model/output
as before.
