Subject: [PATCH] fix(bootstrap): raise tokio worker stack to 16 MiB (issue
 #312)

The worker threads carry the whole planning -> dispatch -> execution
pipeline synchronously; the DDL/index path nests deep enough to exhaust
tokio's 2 MiB default and the process died with a silent SIGSEGV
(CREATE VECTOR/SORTED INDEX dropped the connection; inproc tests aborted
with 'tokio-rt-worker has overflowed its stack'). 16 MiB restores
headroom; tokio reserves the space virtually and commits pages on
demand. Verified: index DDL and the previously-aborting suites pass
without RUST_MIN_STACK.
