feat: accessibility automation v1 (core + tauri + settings)

[senamakel]

Summary

• Added a native rust-core accessibility automation subsystem (macOS-first) with ephemeral in-memory runtime state.
• Implemented new core JSON-RPC methods under openhuman.accessibility_* for status, permissions, session lifecycle, capture, input actions, and autocomplete flows.
• Exposed matching Tauri commands and frontend typed wrappers in tauriCommands.ts.
• Added Redux accessibilitySlice for permissions/session/feature/error state and async lifecycle actions.
• Added first-class Settings route/panel at /settings/accessibility and linked it in settings navigation/home.
• Added Rust and frontend tests for lifecycle, validation, RPC envelopes, reducer behavior, and panel rendering.

Problem

• The app lacked a dedicated, native accessibility automation layer for screen state monitoring, bounded input control, and predictive typing.
• There was no unified core RPC/host/UI surface to manage consented sessions, permission checks, panic stop handling, and runtime status.

Solution

• Implemented rust-core/src/openhuman/accessibility/mod.rs as a process-global engine with:
  • Hybrid capture scheduler (foreground context change + baseline cadence).
  • Session TTL enforcement and explicit consent-gated session start.
  • Denylist-based context blocking and input action validation.
  • In-memory-only capture/context buffers (no disk persistence by default).
  • Predictive autocomplete suggest/commit primitives.
• Added AccessibilityAutomationConfig to core config schema/defaults and wired it into Config.
• Extended rust-core/src/core_server.rs dispatch table with all openhuman.accessibility_* methods and response typing.
• Added Tauri command proxies in src-tauri/src/commands/openhuman.rs, command registration in src-tauri/src/lib.rs, and typed bridge event emission (openhuman:accessibility) with host notifications on key events.
• Added frontend command wrappers/types, Redux slice integration, and a dedicated settings UI panel.

Testing

• yarn -s compile
• cargo check --manifest-path src-tauri/Cargo.toml
• Other checks run (list commands)
• npx prettier --check .
• npx eslint .
• npx tsc --noEmit
• cargo fmt --manifest-path src-tauri/Cargo.toml
• npx vitest run --config test/vitest.config.ts src/store/__tests__/accessibilitySlice.test.ts src/components/settings/panels/__tests__/AccessibilityPanel.test.tsx
• cargo test -p openhuman-core accessibility --manifest-path src-tauri/Cargo.toml
• Manual validation completed (list scenarios)

Impact

• Runtime/platform: Adds macOS-first accessibility automation surface in core; non-macOS paths report unsupported/limited permission status.
• Security/safety: Explicit consent gate, bounded session TTL, denylist checks, and panic-stop action path.
• Data handling: Capture/context state remains ephemeral in memory by default (no persisted frames).
• Compatibility: Adds new config section (accessibility) with defaults; existing config loads remain backward compatible via serde defaults.

Breaking Changes

• None
• Yes (describe clearly, including migration steps)

• Issue(s): N/A
• Follow-up PR(s)/TODOs:
  • Wire true OS-level global panic hotkey registration (current panic stop path is action-driven).
  • Expand native permission interrogation for Screen Recording/Input Monitoring beyond unknown fallback where feasible.
