feat(manifold,firmware): restore uSEQ CV/gate as an Outputs backend Restores the April-2026 "uSEQ-Celium" functionality (browser → uSEQ hardware + CV expander over USB Web Serial) as a first-class Manifold Outputs backend, and re-vendors the RP2040 firmware into the repo. - protocol v2 (uSEQ-CV): firmware/useq-celium/shared/protocol.h is the single source of truth, mirrored by manifold/src/backends/useq-protocol.ts. 26-byte OUTPUT frame, 11×u16 CV (12-bit) + 3-gate bitfield + XOR; fixed topology; host-agnostic so the MEMLNaut RP2350 can emit identical bytes. Spec in docs/useq-celium/protocol.md. - firmware/useq-celium/{main,expander}: PlatformIO RP2040 firmware rewritten to v2 from the real April pin maps (expander I2C addr 0x10). - UseqCvBackend (id cvgate): Web Serial connect/identify/disconnect, 100 Hz stream, per-channel dead-zone, gate thresholding; modeled on midi-backend. Per-output CvSpec (channel + gateThreshold) on MFParam; config UI in OutputsBackendConfig + BackendAdvanced; new "CV / uSEQ" top-dock mode. - bun-test for the protocol frame layout; MAP.md updated. 2026-06-28 21:28:03 +02:00			`; uSEQ-CV expander board — RP2040 (uSEQ USEQHARDWARE_EXPANDER_OUT_0_1)`
