feat: add okr plugin v1.0.0 — OKR guidance for Norwegian public sector

Expert OKR guidance based on Google/Doerr methodology, adapted for
4-month tertial cycles and Norwegian government accountability.

Components:
- 8 commands (skriv, kvalitet, kaskade, sporing, møter, innføring, governance, oppsett)
- 5 agents (kvalitetssjekker, kaskadebygger, fremdriftssporer, møtefasilitator, styringsrådgiver)
- 3 hooks (UserPromptSubmit context injection, PreCompact state preservation, Stop reminder)
- 15 reference files covering methodology, governance, meetings, antipatterns
- Linear MCP integration for OKR tracking

Previously in ktg-privat, now open-sourced.

+### Changed
+- **Architecture**: Commands rewritten as self-contained handlers with embedded domain logic (previously routed to external prompt files)
+- **Agent models**: 4 agents downgraded from opus to sonnet (kvalitetssjekker, kaskadebygger, fremdriftssporer, møtefasilitator); styringsrådgiver remains opus
