perf(extreme-fast-mode): use processed commitment + tight retry for BC refresh

Before: BC fetch in extreme_fast_mode used default (confirmed) commitment
and retried up to 10 times with growing backoff (~10s total). Geyser/logs
fire on processed, so the BC isn't yet at confirmed commitment when the
bot reads it — most fetches failed and burned the full retry budget,
adding ~10s to detect→confirmed.

After: read at processed commitment to match the listener event horizon,
and cap retries at 4 with 150ms gaps (~600ms ceiling). Most reads succeed
on the first attempt.

Mainnet benchmark (n=4 successful buys, geyser listener):
  buy_slot − create_slot: min=2  median=3  max=9  (~0.8s — 3.6s on chain)
  wall detect→confirmed:  median 2-3s (1s resolution)

Best case 2 slots = next slot after creation + tx propagation.
