research: observational instrumentation — bid_top on attempts + markout book re-reads (+60/300/1800s) on both harnesses

No signal-path change (SEM_VER unchanged): records more, alters nothing.
Purpose: real exit marks for the markout-exit study (prints can't show the
bid) + book depth at mispricing moments (maker-study stage-1 groundwork).
oraclebot gains the same append-only attempts log as A2. Nightly pulls the
new files alongside state.
