fix(stdio): short-circuit semantic_search when index is being rebuilt (#163)

When a background indexer holds the index flock, ensureIndexed sets
out.StaleWarning and returns immediately, but handleSemanticSearch then
proceeded to call embedQuery. On a single-instance embedding backend
(e.g. LM Studio) saturated by the indexer's 32-chunk batches, the query
embed queues behind those batches and the MCP call hangs well past
Claude Code's timeout — the user sees an infinite "loading" state and
never receives the warning text telling them to use standard tools for
the next 10 calls.

Reproduced reliably with two parallel semantic_search calls into
different subdirectories of a monorepo while a background lumen index of
the monorepo root holds the flock. After the fix both responses return
in ~0.4s with the StaleWarning text instead of timing out at 100s.
