fix(buf_ls): restrict reuse_client to buf_ls clients only #4221

The previous implementation used `reuse_client = function() return true
end`,
which caused buf_ls to reuse *any* existing LSP client. As a result,
when a
Copilot LSP client was already running, buf_ls attempted to reuse that
client
instead of spawning its own, preventing buf_ls from attaching to .proto
buffers.

Restrict reuse_client so only buf_ls clients can be reused.
