Radar RS Analyst v0.2.1

Radar RS Analyst v0.2.1

Promoted the accepted history/live/portability/velocity work to main.

Highlights:

• Frame history with selectable 3/5/7/10/15/20/25/30 frame limits.
• Timeline scrubber, previous/next controls, and play/pause looping.
• Explicit Load Loop history backfill so normal live loading stays focused on current data.
• Level II live backfill and live partial handling with stale/partial/complete labels.
• Low-level live chunk display is gated by the Chunks option; default waits for a complete low-level tilt.
• Same-site live refresh preserves map view and product selection, including velocity.
• Multi-radar overlays remain available while the primary radar keeps priority.
• RadarScope/analyst-style stepped palette parsing and additional REF/VEL color presets.
• Plain VEL can use the dealiased continuity grid by default via Unfold VEL.
• Portable cache/config paths; no Drew/source-tree runtime path dependency found in source or release EXE audit.
• Profiling examples for single and multi-radar decode/render/memory checks.

Verification:

• cargo test -p render2d -p app_ui -p color_tables -p data_source
• cargo build --release -p app_ui with path remapping
• Source hardcoded-path audit passed.
• Release EXE binary string audit passed for Drew/Codex/Downloads/source-tree paths.

Known caveat:
The velocity dealiaser is still a lightweight local implementation, not a full GR2A/RadarScope-grade dealiaser. It is improved for obvious folded-core and unsupported ray artifacts, but complex velocity regions can still differ from commercial tools.
