fix(lsp): handle providers without subcapabilities

Browse Source 
Previously, the LSP client assumed all providers had subcapabilities,
which could cause issues when a provider did not. This change adds a
check for the presence of subcapabilities before attempting to access
them, ensuring correct handling of both cases. This improves
compatibility with servers that register providers without additional
capabilities.
