Extract the tun and tunnel protocol blocks from InboundFormModal into inbounds/form/protocols/{tun,tunnel}.tsx (presentational, declarative). First inbound-side per-protocol split. Verbatim relocation; inbound snapshots unchanged -> no behavior change. typecheck/lint/build green.
InboundFormModal.tsx 3129 -> 2863. Moved AdvancedSliceEditor and AdvancedAllEditor (the in-modal JSON slice/all editors) into advanced-editors.tsx along with their adapter-helper imports. Per-protocol render snapshots unchanged -> verified no behavior change. typecheck/lint/build green.
Decouple Outbound from Inbound schemas: SSMethodSchema and VmessSecuritySchema (shared between inbound & outbound) now live in a neutral schemas/protocols/shared/ module. Outbound no longer reaches into schemas/protocols/inbound/*. Pure relocation + import rewiring; schema values identical, snapshots & golden tests unchanged.
