Greptile Summary

This PR adds a new fundamentals/client-support.mdx page and registers it in the navigation. The page consolidates per-client feature availability, runtime mapping, connection requirements, and client-specific setup notes in one place.

• New documentation page with a feature matrix (✅/⚠️/❌) covering ChatGPT, Claude, Goose, and VSCode across all Skybridge hooks, plus a DevTools runtime coverage table and client-specific notes sections.
• docs.json updated to add fundamentals/client-support as the third entry under the Fundamentals nav group.

Confidence Score: 4/5

Safe to merge — purely additive documentation with no code changes.

The content is accurate and consistent with the existing mcp-apps.mdx reference page. Two small clarity gaps exist: the ⚠️ symbol in the feature matrix has no inline legend (its meaning is only revealed further down the page), and Postman/MCPJam appear in the Client Overview table but are silently dropped from the feature matrix. Neither affects correctness, but both could confuse readers consulting the table in isolation.

docs/fundamentals/client-support.mdx — feature matrix legend and Postman/MCPJam coverage.

### Issue 1 of 2
docs/fundamentals/client-support.mdx:28-29
The feature matrix uses ⚠️ without defining what it means at the point of reference. A reader scanning the table won't know whether ⚠️ means "partial support", "experimental", or "polyfilled" unless they scroll down to the Client-Specific Notes — or happen to have read `mcp-apps.mdx` first. Adding a one-line legend beneath the table header keeps the page self-contained.

```suggestion
✅ Supported · ⚠️ Polyfilled (works with limitations) · ❌ Not supported

### Issue 2 of 2
docs/fundamentals/client-support.mdx:28-43
**Postman and MCPJam absent from feature matrix**

The Client Overview table (lines 11–18) lists six clients including Postman and MCPJam, but the Feature Availability matrix only covers four (ChatGPT, Claude, Goose, VSCode). Since both Postman and MCPJam are listed as full MCP Apps clients their feature columns would be identical to Goose/VSCode, but their omission leaves readers uncertain. Either add their columns to the matrix or add a brief note explaining they share the same feature set as other MCP Apps clients.
