* fix(providers): launch plugin CLIs on Windows and tolerate Muse startup
Plugin providers bypassed the core Windows launcher and the plugin host exposed an empty server SDK module. Share the launcher through the SDK and bind it in the host. Give Muse initialization its own deadline because native startup traverses session history before answering MSP.
* fix(providers): terminate Windows launcher process trees
A command-script launcher leaves the CLI behind cmd.exe. Expose forced process-tree termination in the server SDK, use it for Muse and SDK ACP teardown, and bound Muse closing so inherited streams cannot leave callers waiting forever.
* test(muse): keep platform setup outside the teardown assertion
* refactor(plugin): expose process capabilities without quoting helpers
* fix(providers): close process trees on uncorrelated protocol errors
* Revert "Remove the unreleased Antigravity provider plugin (#5781)"
This reverts commit 9d9d9af993.
* fix(providers): commit plugin notices emitted during session opening
* feat(providers): restore Antigravity with full access and session warnings
* fix(providers): warn once when opening Antigravity sessions
Driver respawn retains the live transcript and unchanged permission posture. Emit the warning only when opening a session, including resume after a daemon restart.
* refactor(providers): remove the unreleased Antigravity plugin
Remove the provider at the owner’s request because headless command approvals are unsupported. Preserve Muse, shared plugin infrastructure, and earlier editor and terminal integrations.
* test(plugins): keep builtin startup coverage generic
* test(antigravity): record agy stream-json fixtures
* feat(antigravity): add Antigravity provider plugin
* fix(antigravity): address Phase 1 review findings
* test(antigravity): record parity discovery blockers
* feat(antigravity): support image prompts and daemon e2e
* docs(antigravity): document provider setup and limitations
* test(antigravity): respect Windows interrupt semantics
* docs(plugins): avoid duplicate provider override guidance
* fix(antigravity): report fresh denials and correct mode metadata
Native denial results accumulate within a driver process. Track reported occurrences until respawn so later text-only turns do not repeat notices, while new denials of the same action remain visible.
* fix(antigravity): use the official Antigravity mark
