feat(gui): add capability-driven actions ring

[jericho0521]

Summary

Adds a capability-driven Actions Ring vertical slice, including MX Master 4 Haptic Sense Panel capture, agent-owned sessions, haptic feedback, a warm non-activating GPUI overlay, and an editor for radial actions.

Changes

• core: add Actions Ring layouts, per-application overrides, custom presentation icons, typed keyboard shortcuts, and application/folder/URL targets
• hidpp/hid: add reverse-engineered 0x19B0 haptic feedback and 0x19C0 force-sensing wrappers; discover and divert Haptic Sense Panel CID 0x01A0; preserve prior reporting state
• hook/inject: expose cross-platform cursor positions and execute typed shortcuts or expanded application/path targets
• agent/ipc: add validated, snapshotted ring sessions with expiry, hover deduplication, cancellation, activation, and haptic playback; bump the positional protocol to version 13 with wire goldens
• gui: add an eight-slot radial editor, categorized action library, 53 custom icon choices, shortcut/path inputs, and the warm circular overlay without focus activation or native window borders/shadows
• packaging: ship and sign openlogi-overlay in macOS, Linux, and Windows artifacts
• i18n/docs: localize the new UI across all locale files and document schema version 3 Actions Ring configuration

The 0x19B0, 0x19C0, and CID 0x01A0 behavior is documented in code as reverse-engineered rather than treated as an official protocol guarantee.

Screenshots

Pending: macOS Screen Recording is unavailable to the development harness. The editor and overlay were runtime-tested locally, but a maintainer-captured screenshot still needs to be attached.

Testing

• cargo fmt --all -- --check
• cargo clippy --workspace --all-targets -- -D warnings
• cargo test --workspace
• cargo run -p xtask -- macos bundle
• codesign --verify --deep --strict --verbose=2 target/release/bundle/osx/OpenLogi.app
• launched the development and release-shaped app bundles on macOS 26.4 arm64
• verified GUI, agent, and warm overlay processes launch together
• verified selecting a radial slot and assigning Left Click persists the expected slot configuration
• verified every custom gallery icon resolves to an embedded asset
• verified the release-shaped local bundle can replace the installed application
• MX Master 3S detection was runtime-tested
• not runtime-tested on MX Master 4 hardware: CID 0x01A0 capture, waveform playback, force thresholds, and press-to-first-frame latency remain to be verified
• not runtime-tested on Linux or Windows; CI is required for cfg-gated behavior
