0.1.0-beta.1

New beta release; bugs may remain.

• OP-only preview and confirmation for temporary plain sign text.
• Separate sign-side lease markers and conflict-safe restoration.
• Bounded atomic world ledger, restart persistence and unloaded-chunk deferral.
• Original supported text, filtered lines, dye and glow retained.

Exact final production JARs passed dedicated-server startup, 27 installed gameplay assertions and a separate-process saved-world restart with four restoration assertions on each supported version. The pure ledger suite passed 207 assertions on Java 21 and 25. Tests include actual registered preview/confirm commands, raw/filtered original lines, dye/glow, newer edits, opposite-side edits, wax/editor conflicts, replaced/broken signs, unloaded deferral then loaded restoration, expiry, permission rejection, and persisted lease markers. Graphical-client and real remote-player session testing were not performed.
