08c92bfefb Add tiered .asc parser with companion netlist resolution
Implement three-tier resolution for LTspice .asc schematic files:

1. Companion netlist - finds .net/.cir/.sp beside the .asc (automatic)
2. LTspice generation - invokes LTspice binary (opt-in via --generate-netlist)
3. Metadata-only fallback - extracts component refs/values without connectivity

Safety: DataCompleteness enum forces callers to check completeness.
CLI blocks diagram generation on METADATA_ONLY with clear remediation.
Metadata enrichment is additive-only with protected field guards.

Also: update project URLs to Gitea, add .asc usage docs to README,
fix pre-existing ruff warning in test_single_module.py.

c2197f6fe6 Add star-topology layout optimization for single-module diagrams
Three-pass optimization eliminates cable crossings:
1. Order boundary components by average header pin position
2. Regroup header pins by boundary component (reduces inter-cable crossings)
3. Reorder boundary component pins to parallel header (eliminates within-cable
   crossings)

Safety hardening from Apollo review:
- Duplicate header pin deduplication (prevents silent mapping corruption)
- Connection structure validation at entry
- Fan-out averaging for component pins connected to multiple header pins
- Explicit ValueError on pin remapping failures with diagnostic context

145 tests passing (was 130).
