pi-fold 4.2.3

pi-fold 4.2.3

Floor the fold bar's usage label to match pi-cc's footer. Use Pi's original getContextUsage() percentage directly, avoiding floating-point round-trip drift at values such as 29%, 57% and 58%.

Apply the same formatting to live, stale, stopped and widget-less usage labels. Preserve unrounded bar fill, nearest commit-point labels and all folding thresholds and trigger timing.

Extend gate 177 for fractional and integer-edge percentages, unchanged fill and all display variants. Update the README and genuinely re-extract the sealed evidence with unchanged research findings.

Validation: lint, all 72 runtime gates, all 118 experiment gates, README/DOI checks and the exact 24-file package allowlist.
