defaultClientCapabilities
constdefaultClientCapabilities: () =>ClientCapabilities
What every client of this package declares, before a host adds anything of its own.
There is deliberately no textDocument.semanticTokens block here, and adding one would be a
mistake rather than a convenience. The content of that block is the host’s — a real server
computes its advertised legend as the intersection of its own token types with the ones the
client declared, which makes the declared block an input to the server rather than a local table
— and declaring it at all commits every server the client speaks to to computing tokens. A host
that paints no semantic colour would be paying for answers nobody draws. Hosts that do want them
build a block with semanticTokensClientCapability() and pass it in as capabilities.
