Native mode (from DB config) was not accounted for when sizing the
connection pool or setting SLEEP_QUEUE, because both read NUM_WORKERS
from env which is never set when native mode is configured via the
worker group config in the database.
- Resolve native mode early (before connect_db) by querying the config
table with the initial DB connection
- Pass num_workers directly to connect_db instead of re-reading env
- Replace SLEEP_QUEUE lazy_static with sleep_queue() function that
checks NATIVE_MODE_RESOLVED at runtime (returns 300ms for native)
- Set NATIVE_MODE_RESOLVED immediately when is_native_mode_from_env()
- Allow native_mode in CE worker group config (was silently stripped)

Add new BENCHMARK_KIND variants (sequentialflow, scriptlogs, concurrencylimit,
concurrencykey, mixed, mixed_no_cc) for targeted performance testing. Fix shared
iteration counting across workers using a global atomic counter. Add job_perms
inserts and queue diagnostics for benchmark mode.
Move db connection setup to dedicated module and drop the initial connection pool
before creating the main one, preventing connection starvation when PostgreSQL
max_connections is low.
