Three coupled changes so kicad-cli sch erc runs at the project level
(across all sheets of one schematic) instead of single-sheet:
1. (label) → (global_label (shape passive)). EPRO2 nets are
project-global by construction (named rails span every page in the
SCH and physically wire across PCBs); KiCad's local label is sheet-
scoped and triggers `label_dangling` for any name not duplicated on
the same page.
2. New root_sch_writer that groups SCH_PAGE docs by their parent SCH
(META.schematic), emits one root .kicad_sch per group with one
(sheet ...) entry per child, and threads the root-assigned uuid back
into each child's (sheet_instances) so KiCad can bind them.
--all-sch now defaults to this; --flat falls back to one-file-per-page.
3. EPRO2's "5-Voltage" placeholder COMPONENT (partId
pid8a0e77bacb214e, 365 instances on ESP-VoCat) is the editor's power
port. The rail name lives in the placement's `Global Net Name` ATTR,
not in the PART. We now emit a (global_label "<rail>") at the
placement coords whenever that attr is set (101/365 of them on
ESP-VoCat — the rest are unconfigured drafts).
ESP-VoCat 5 hierarchical roots: 2325 → 2265 violations. Modest because
5 of 6 SCHs are single-page (no cross-sheet nets to resolve), and the
one 4-page schematic (CoreBoard) shares only a handful of names across
sheets — most net names are de-facto sheet-local. The remaining ~190
pin_not_connected are dominated by 0402-style passives whose pin tip
lies on a wire's interior, not at an endpoint; KiCad needs an explicit
(junction) at those points and we don't yet emit one. Marked as the
next follow-up in log.md.
47 → 52 unit tests pass.
