JUSDecomp 0.2.1 — online FPS fix

Online WiFi Battle now runs at ~60 fps (was ~35). Root cause: the WFC/DWC network stack (ARM9 ov008/ov010 + ARM7 wifi driver) ran on the Tier-3 interpreter because the online launchers never enabled live-overlay promotion. Full write-up: decomp/docs/ONLINE_FPS.md.

What's new

• GUI launcher now enables live-overlay promotion in online mode, pointing at the bundle's pre-seeded app/live-cache.
• WFC profile persistence — friend codes survive relaunches (--firmware-state-path under the user dir).
• Online mode (Wiimmfi) is on by default — just type a player name.
• Pre-seeded release bundle — every ROM overlay page is pre-compiled to native (328 pages / 328 DLLs), so the game boots fully native with no in-session convergence wait.
• The .cmd/.sh online launchers also enable live-overlay promotion (per-instance caches for 2P).

Known issue

Occasional sub-second micro-stutters during online play remain (documented in decomp/docs/ONLINE_FPS.md).
