docs(openspec): propose planner-route-encoding change

Browse source 
Follow-up to the planner WS reconnect-loop incident. Proposes compactly
encoding the computed route in the Yjs session doc (single-source geometry
+ delta/varint polyline + run-length-encoded road metadata, dual-format
backward-compatible reads) to cut a ~305 KB / 77 km route to ~40–60 KB —
WITHOUT changing the routing-host "compute once, share via Yjs" model or
GPX export output.

Artifacts: proposal, design, specs (new planner-route-encoding
capability), tasks. Validates --strict. Ready for /opsx:apply.
