`runNetlist` was guessing what vectors to read by regex-matching
`V*/R*/L*/C*/D*/Q*/M*` lines in the netlist string. Fragile —
missed extra-card nets, custom prefixes, subckt-internal nets.
This commit gives the Worker adapter the same enumeration surface
the Node adapter already had:
• New `listVectors` message type in the worker, calling
`ngSpice_AllVecs(curPlot)` and decoding the NULL-terminated
char** result. Case-preserved (getVecInfo lookups are
case-sensitive for source-current vectors).
• `NgSpiceInteractive.listVectors()` exposes it to the adapter.
• `NgSpiceWorkerAdapter.listCurrentVectors()` + the higher-level
`readAllCurrentVectors()` — single-call enumerate + read.
• `runNetlist.ts` simplified: ONE solve, then read every vector
via the adapter. No more regex parsing. No more guess-set.
`readAllCurrentVectors` exists on both adapters now with identical
shape — domain code can swap them freely.
1461 tests pass. Both `examples-gallery-smoke` (68 examples) and
`circuit-verifier` (8 pre-flight checks) green.
