François fe5b2c3d96 P3.2: source precedence + model-vs-netlist conflict check ...

Rank the spec sources (spec_source_rank: UserOverride > Bsdl > ConnectorModel
> Inferred > Imported); apply_model now refuses to overwrite a spec owned by a
higher-rank source, so one model never clobbers a more authoritative one. New
check_source_conflicts(System*) emits SourceConflict for a pin the BSDL
declares power/ground (a must-connect rail) that the netlist leaves
unconnected — a rail floated in the schematic; surfaced as a sixth `verify`
pass. Unit tests (75 cases) green; the real 8-card system reports 0 conflicts
(its rails are all connected) while the JTAG findings remain.
