The contract test only checked one direction (each name in
HOST_CONTRACT_METHODS exists on the real DocmostClient). But
HOST_CONTRACT_METHODS is itself a hand-copy of the server's
DocmostClientLike interface (docmost-client.loader.ts), and that
list<->interface link was untested: a method added to the interface +
consumed by the adapter but forgotten in the list (or removed from the
interface but left in the list) would escape both the server typecheck
(the pkg emits no .d.ts) and the existing test (name not in the list) ->
a runtime "x is not a function" in a tool call.
Parse the method names from the DocmostClientLike interface body (read
the .ts source via import.meta.url, scan member-signature lines) and
assert.deepEqual them against HOST_CONTRACT_METHODS BOTH ways. Lists are
currently identical (39=39), so this is a coverage hole closed, not a
live bug.
