Rebuild the PicoCalc F-key lane per JP's spec: five fixed 9-cell chips (F1 DESCRI, "10" standing in for the overflow F10 label), gray fill on the plain F1-F5 bank and green while Shift's bank is showing, white text on both. DEFAULT_LANE moves to an adjacent-plain-key priority model: commit/leave take the easiest- to-reach F4/F5 with no Shift needed, jump-to-top/end take F1/F2 with paging as their Shift companions, and F3 stays the one lone slot a screen's own lane reaches for first. FPair's Shift half is now optional, so a lone slot renders blank in the shifted bank instead of forcing an unrelated opposite action onto it. Also bridges the on-device quirk where the MCU's F6-F10 translation can appear to release Shift an instant before the translated code lands, flipping the lane back mid-chord: modifier_watch now latches shift_down() true for a short grace window after any F6-F10 press resolves, on top of the raw watcher state.
