v0.8.7: tool capability metadata, in-process engine, Qt app, Android engine
The engine can be embedded now instead of only driven from a terminal: the same objects link into a Qt front end (app/) that owns a cst_agent_t inside its own process -- no port, no token, no second process -- and that front end now runs on the desktop and, engine-side, on the phone. Capability metadata (include/cst_tools.h, src/tools/registry.c): - cst_tool_def_t gains perm_name, platforms and available (a probe that returns a reason), so a permission is addressable by name and a tool can say why it cannot run here. - cst_platform_name(), cst_tool_platform_ok(), cst_tool_available(), cst_tool_meta_reload(), cst_tool_perm_name() and CST_PLAT_DESKTOP[]. - cst_tool_register() may take over a built-in name that is not runnable on this platform, so a front end replaces it with its own implementation. - the registry entries carry their class (delete_file -> "delete"), the desktop clipboard tools carry a clipboard probe; find/active/run gate on it. - /api/settings.tools[] exposes perm_name, platforms, available, why and the declared parameters. Engine as a library (Makefile, CMakeLists.txt): - libcstcore.a from the CORE_OBJ set, and a CMake cstcore target shared by the CLI and by app/ (-DCST_BUILD_APP=ON): the engine is compiled once. - Android branch for the vendored sashidown: a per-ABI archive built with the NDK's aarch64-linux-android24-clang wrapper, because CMake's compiler is plain clang and keeps --target/--sysroot in its own variables. Qt front end (app/, new): - AgentCore wraps one cst_agent_t: turns run on a worker thread, every cst_agent_hooks_t callback becomes a Qt signal, and the two hooks that need an answer (on_permission, on_ask_user) block the worker until the GUI replies; mode, approval and plan mode go through the engine's config. - ToolProvider hands the front end's tools to the engine (owner "app:*"); the Linux one is notification_send with a probe for notify-send/D-Bus. - Main.qml: transcript, tool blocks, consent dialog (Deny/Once/Always -> CST_PERM_*), ask_user, mode switch, Esc to cancel; --selftest stays headless and runs the embedding checks without QML. Android (scripts/, docs/android.md, new): - scripts/build_third_party_android.sh builds static mbedTLS + libcurl for an ABI (CA path /system/etc/security/cacerts); build_android.sh builds cst-agent, libcstcore.a and the test binaries for the phone, can push them and run the whole suite there. - sandbox_exec.c keeps the plain exec path on Android: the seccomp supervisor compiled in and the probe reported "seccomp", but writes outside the workspace were not denied on the device -- claiming a sandbox that does not hold is worse than reporting none. - tests/test_diff.c compares layouts only against real GNU diffutils: toybox's diff prints the same hunk header with its own hunk/context rules. Tests: test_tool_meta (metadata, platform gate, probe reasons, takeover of a built-in name) and test_embed (in-process embedding contract) are new; the existing registry/llm_body assertions now follow availability. 38 test binaries pass on the host, 36/36 on arm64-v8a Android 16, cst-app-selftest passes in both the standalone app/ build and the repo build. Version 0.8.7.
