feat(adapters): add capability flags to ServerAdapterModule

Replace 5 hardcoded adapter type lists with declarative capability flags
on ServerAdapterModule, enabling external adapter plugins to declare
their capabilities without modifying Paperclip source.

New optional fields on ServerAdapterModule:
- supportsInstructionsBundle: managed instructions bundle support
- instructionsPathKey: config key for instructions file path
- requiresMaterializedRuntimeSkills: skill materialization needed

Server changes:
- agents.ts: capability-aware helpers with legacy fallbacks
- adapters.ts: expose capabilities in GET /api/adapters response
- registry.ts: explicit flags on all built-in adapters

UI changes:
- New useAdapterCapabilities hook for capability lookups
- AgentDetail.tsx: replace hardcoded isLocal allowlist
- AgentConfigForm.tsx: replace NONLOCAL_TYPES denylist
- OnboardingWizard.tsx: replace NONLOCAL_TYPES denylist

All flags are optional with backwards-compatible fallbacks to the
legacy hardcoded lists for adapters that don't set them.
