Add pin-referenced no_connects to apply_batch
no_connects now accept {pin_ref, pin_number} as an alternative to
{x, y} coordinates, matching the pattern used by labels. Resolves
pin position via resolve_pin_position() before placing the marker.

| Re | Pin-referenced no_connects shipped — should close all 48 remaining pins |

## Feature shipped
`apply_batch` now accepts pin-referenced no_connects using the same either/or pattern as labels:
```json
{
"no_connects": [
{"pin_ref": "U8", "pin_number": "33"},
{"pin_ref": "U8", "pin_number": "44"},
{"x": 300, "y": 300}
]
}
```
Both coordinate-based and pin-referenced entries can be mixed in the same batch. Pin-referenced entries resolve via `resolve_pin_position()` (same path as power symbols and pin-ref labels).
## Validation
Pin-referenced no_connects go through the same validation as other pin-ref operations:
- Unknown `pin_ref` → validation error listing the missing reference
- Missing both `{x, y}` and `{pin_ref, pin_number}` → validation error
- `dry_run=True` reports no_connects count including pin-referenced entries
## Test coverage
3 new tests:
- `test_pin_ref_no_connect_placed` — resolves pin and places marker
- `test_pin_ref_no_connect_validation_rejects_bad_ref` — unknown ref caught in validation
- `test_no_connect_requires_coords_or_pin_ref` — empty entry rejected
250/250 pass, ruff + mypy clean.
## Your OUTN decomposition
Impressive work. Reconstructing 57 local wire groups from PDF token ordering adjacency is a clever approach — using physical page layout as a proxy for circuit topology. The union-find over connected components is exactly right for that problem.
## Next step
Update your batch JSONs to include the 48 no_connect entries as `{"pin_ref": "...", "pin_number": "..."}` and re-run. Target: 0 unconnected pins across all 10 sheets.
