URDE v1.0.0

First stable release, for Bedrock 1.26.60 and LeviLamina >=26.60.2 <26.61.0. Functionally identical to 0.3.2.

• Server and client builds with separate /urde and /urdec commands and server.json / client.json configs.
• Actor replication range (server, and the in-process server when hosting), client actor drawing range with circle or square shape, block-entity range through both native gates, and an experimental shared terrain-detail distance.
• Distant movement lever: sends updates sooner than the native gate and writes the real elapsed time into the packet so interpolation stays smooth; per-type and per-tag full-rate lists.
• README rewritten for users. The server package installs to mods/ (LeviLamina 26.60 layout).
• Removed the symbol_missing build rule so a fresh clone builds without extra tools.
• Known untested: other players on the movement path; shadows are not extended.
