OPA v0.2.1 — Performance & UI Fixes

Performance

• Removed per-item BackdropFilter blur from all scrolling list items (connection cards, key cards, command cards, info banners, quick-command chips). These blurred a flat solid background for zero visual gain but caused heavy per-frame re-rasterization — the main source of scroll/navigation jank.
• Removed staggered per-item entrance animations from the agent-harness preset chips (21 animation controllers across the Agent / DevTools / System rows) and per-row fadeIn/slide from cards. This resolves the laggy feel in the Quick Commands preset panel specifically.
• Fixed an N+1 Hive box scan — listProfiles() now runs once per screen instead of once per command.

UI Fixes

• Fixed the auth selector overflow — the Password / Key / Both SegmentedButton text no longer overflows its segment (icon 16→14, label font→12, tighter padding).

Verification

• flutter analyze: no new issues
• 38/40 tests pass (2 pre-existing failures in ssh_key_encoder_test, unrelated)
