Release v4.115.0

Changed

• Recorded the exact public CLI 3.40.3 and Stage 4.49.5 browser acceptance rerun as a new partial released vector while preserving the older Stage 4.49.2 partial receipt. (part of #168) (part of #173)
• Hardened the browser harness to continue after missing native form fields and record form-control descriptors when Stage exposes command controls without fillable inputs. (part of #168) (part of #173)
• Captured the remaining Stage 4.49.5 runtime blockers for scoped comments, selected-row query identity, deep links, stale response discard, invalid native submit suppression, native form fields, and theme application. (part of #168) (part of #173)
