Radar RS Analyst

Radar RS Analyst v0.2.2 Supersedes v0.2.1 with the accepted history/live/portability/velocity work plus the extra velocity-dealias spoke guardrails from review. 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. - Velocity dealias spoke guardrails: radial unfold cap reduced, stale slope propagation after gaps blocked, and isolated spoke cleanup retained. - 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 velocity_dealias -- --nocapture - cargo clippy --all-targets --all-features -- -D warnings - 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 now has additional radial-spoke guardrails, but complex velocity regions can still differ from commercial tools.
