add editor subsystem — daemon state + editor.* IPC
EditorBuffer + Selection + EditorRegistry hold the daemon-side active-file model (D-006 subsystem 'editor'). Active buffer tracking means `clide insert "…"` and `clide replace-selection "…"` target the UI's focused file without the caller supplying an id. Mutations mark buffers dirty; editor.save writes back to disk through the workspace root; events fire on every state change so subscribers can mirror. IPC surface matches CLAUDE.md's tier-2 list + the natural extras (list, read, activate, set-selection, set-content, close). Tests cover open-idempotence, insert at caret, replace-selection range swap, dirty→save→clean round-trip, close picks a new active buffer, out-of-range selection clamping. 69 core tests pass.
