The single "(file missing, wrong magic, or schema mismatch)" message
was making triage harder than necessary. loadSidecar now expands a
leading ~/ (shells skip it inside double quotes, which trips up paste-
from-launcher), and on failure peeks the file's header itself to
report exactly which check failed:
- "Sidecar not found" — file doesn't exist
- "Sidecar unreadable" — exists but open failed
- "Sidecar truncated" — <12 bytes
- "Sidecar magic mismatch" — wrong magic, reports got vs expected
- "Sidecar schema mismatch" — wrong version, reports both numbers
and suggests re-baking
- "Sidecar endianness mismatch" — cross-platform load attempt
