* make registerAppTool more interchangeable w/ server.registerTool
* feat: use structuredContent in all example servers
All servers now return structuredContent alongside JSON text content.
All mcp-apps now read structuredContent directly (no JSON.parse fallback).
Updated servers:
- basic-server-vanillajs
- budget-allocator-server
- cohort-heatmap-server
- customer-segmentation-server
- integration-server
- scenario-modeler-server
- system-monitor-server
- threejs-server
- video-resource-server
- wiki-explorer-server
* feat: add outputSchema to all example servers
Define output schemas for structuredContent validation:
- basic-server-vanillajs: { time: string }
- budget-allocator-server: BudgetDataResponseSchema
- cohort-heatmap-server: CohortDataSchema
- customer-segmentation-server: customers/segments schema
- integration-server: { time: string }
- scenario-modeler-server: templates/defaultInputs schema
- system-monitor-server: SystemStatsSchema
- threejs-server: { code, height }
- video-resource-server: { videoUri, description }
- wiki-explorer-server: { page, links, error }

* prettier:fix
* revert: remove unrelated workflow, version, and arch changes
* chore: update package-lock.json
* refactor(basic-server-vanillajs): address PR review comments
- Simplify server.ts to return plain time string in text content (not JSON),
matching the quickstart guide pattern
- Add defensive coding in mcp-app.ts with optional chaining and fallback
to handle potential type mismatches gracefully
* refactor: restore rich text formatting for LLM-readable content
Restore the human-readable text formatting functions that were removed,
providing meaningful summaries in the text content while keeping
structuredContent for programmatic UI consumption:
- budget-allocator-server: formatBudgetSummary with config overview
- cohort-heatmap-server: formatCohortSummary with retention stats
- scenario-modeler-server: formatScenarioSummary with financial metrics
