Add board and worker discovery for the Wrighty skill

[highbyte]

Agents need enough board and worker context to assess whether an item may already be picked up before proposing another worker. This adds read-only wrighty workers and wrighty workers --item <id> discovery, with registered-run identity, liveness, effective startup settings, remaining allowance, and advisory pickup reasons. Missing or unverifiable evidence remains unknown; inspection does not claim items or probe agent providers.

wrighty list --json keeps its result array and adds configured status order and listing scope metadata. The bundled Wrighty skill uses these commands for board overview and worker triage. Existing status JSON remains compatible. Worker launch/control and board action execution are follow-up work.

Validation:

• 2,393 .NET tests, 96 JavaScript tests, and 8 packaging tests passed.
• Built CLI smoke test exercised list metadata and discovery of a real idle worker through its automatic exit, with no vendor invocation or tracker changes.
• Skill validation and local static analysis passed for the changed code.
