Add tiered .asc parser with companion netlist resolution

Browse source 
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.
