lmcp: 1.1.0 -> 1.1.1 (bug fix: empty inputSchema.properties)

Tracks upstream lmcp v1.1.1 (commit 9707f7a). Single-bug-fix
release: lmcp:tool() now normalises empty inputSchema.properties
by dropping the key, so Zod-strict MCP clients don't reject
tools/list with "expected: record, received: array".

Discovered live on a hertz-tools deployment where two custom
no-arg tools tripped the check and caused Claude Code to mark
the endpoint as disconnected.
