* feat(apps): add isAppTool helper in core (#1260)
Adds @modelcontextprotocol/ext-apps as a dependency (root + clients/web)
and a thin core/mcp/apps.ts wrapper exposing:
- getAppResourceUri(tool): re-export of getToolUiResourceUri so all
Inspector clients consume the same nested/flat _meta resolution.
- isAppTool(tool): boolean predicate built on top of getAppResourceUri.
Both surface the underlying ext-apps throw on a malformed _meta.ui.resourceUri
(string that does not start with "ui://") rather than swallowing it — server
bugs should be visible.
Tests cover nested format, deprecated flat format, nested-wins precedence,
missing _meta, and the invalid-URI throw.

* test(apps): address PR #1272 review feedback
- core/mcp/apps.ts: convert getAppResourceUri from a typed const re-export to
a function declaration so its export style matches isAppTool. Behavior is
unchanged.
- core/mcp/apps.ts: document the filter-iteration implication on isAppTool —
callers using tools.filter(isAppTool) will halt on a server-malformed URI.
- apps.test.ts: add the symmetric isAppTool false-case for `_meta.ui` present
without `resourceUri`.
