Connect the end-game chart segments end to end - #144
Merged
Conversation
Each chart segment ran from (px+1, previous value) to (px, new value), so consecutive segments never shared an endpoint: at every column boundary the curve jumped by one sample. Inside a 1 px column at 1:1 that is invisible, but with fullscreen scaling each column is several pixels wide and steep slopes render as a row of disconnected dashes. Draw from (px, previous value) to (px+1, new value).

Reviewed the focused diff and validated it against current master. The combined set applies cleanly after the five already merged fixes and builds successfully on macOS arm64; this PR has green Ubuntu 22.04, Ubuntu 24.04, and Windows CI.

Superseding provisional compile-only approval while behavior-focused testing is completed.

Reviewed against current master. Isolated build passed; ASan/UBSan focused checks passed; randomized headless engine smoke test started successfully. The one-line endpoint correction is self-contained and low risk.

Cherry-picked bugfix from PR #132 (fix/fullscreen-scaling), split out to shrink #132/#129's diff against master per Leo's request.
Each chart segment ran from (px+1, previous value) to (px, new value), so consecutive segments never shared an endpoint, producing a broken-looking chart.
