fix(ci): export LIBSQLITE3_FLAGS with SESSION + PREUPDATE_HOOK

host's session/changeset subcommand links against sqlite3session_*
+ sqlite3changeset_* which require the SESSION + PREUPDATE_HOOK
features in libsqlite3-sys's bundled amalgamation. The local dev
flow gets these via the [env] block of .cargo/config.toml (created
by scripts/setup-cargo-config.sh from the template). CI doesn't
run that script + .cargo/config.toml is gitignored, so the
amalgamation compiled without the flags and host's link failed
with 'undefined symbol: sqlite3session_attach' (+12 more).

Mirror the template's LIBSQLITE3_FLAGS line directly into ci.yml's
workflow env. Wasm-smoke is unaffected (already runs the setup
script alongside the wasi-sdk download).
