remove dissolved daemon, retire ptyc, fix golden cross-platform

Complete three overdue cleanups discovered during macOS health check:

D-56 daemon dissolution: delete bin/clide.dart, DaemonServer,
and orphaned tests (test/cli/, subprocess_test, in_process_test).
Update stale "clide --daemon" references in i18n catalogs, error
messages, editor_commands, CI scripts, and decision records.

ptyc retirement: delete ptyc/ source tree, PtySession, scm_rights.
Remove from Toolchain resolution, ToolCheck gate, backend
serialization, testmode harness, Makefile, CI, and sandbox
entitlements. PTY spawning uses NativePty (Dart FFI forkpty) since
the terminal was absorbed in-tree. D-5 amended.

Golden tests: wire the existing but never-applied clideGoldenConfig
via flutter_test_config.dart. Disable CI goldens (Skia anti-aliasing
differs between macOS/Linux even with Ahem). Keep platform-keyed
goldens only — goldens/linux/ and goldens/macos/ each run on their
own OS.

Test suite: 826 pass, 0 fail on macOS (was 829 pass, 11 fail).
