refactor(registry): move MCP servers from code to JSON manifests (#1144)

* refactor(registry): move MCP server entries from code to JSON manifests

Move 8 hardcoded MCP server RegistryEntry structs from
builtin_entries() into data-driven JSON files under
registry/mcp-servers/, matching the existing pattern used by
tools and channels. Exclude the GitHub MCP entry which conflicts
with the WASM GitHub tool's OAuth flow.

Extend ManifestKind with McpServer, make version/source optional
on ExtensionManifest (MCP servers don't need them), and add
url/auth fields for MCP-specific config. Update build.rs,
embedded catalog, catalog loader, installer, and CLI display
to handle the new kind and optional fields.

* fix(registry): address PR review — add missing slack-mcp, remove .expect(), fix fmt

- Add missing slack-mcp.json (was dropped during migration)
- Remove production .expect() in get_strict(), replace with .ok_or_else()
- Clean up unwrap_or_default() in key_for() to use .next() directly
- Log warning for MCP manifests missing url field instead of silent empty
- Run cargo fmt to fix formatting diffs

* ci: re-trigger CI with correct base branch (staging)

* fix(ci): improve no-panics check to properly exclude test modules

The grep-based filter only excluded lines literally containing
#[cfg(test)], #[test], or 'mod tests' — not lines *inside* test
modules. Use awk to track hunk context from diff @@ headers and
skip all added lines within test module hunks.

* refactor(registry): remove slack-mcp MCP entry (conflicts with WASM slack tool)

Remove slack-mcp.json alongside the already-excluded github MCP
entry — both conflict with existing WASM tools of the same name.

* fix(registry): address re-review — skip invalid MCP entries, fix install order

- to_registry_entry() now returns Option<RegistryEntry>; MCP manifests
  missing a url field are skipped with a warning instead of creating
  broken entries with empty URLs
- Move McpServer early-return before require_source() in install paths
  so the error message is clear ("cannot install MCP servers") rather
  than the misleading "missing source spec"
- Add test for MCP manifest with missing URL returning None
