* feat(claude): account for /advisor escalations under the advisor model
Claude Code's advisor tool (/advisor) escalates hard decisions mid-turn
to a stronger model. Those tokens are recorded inside
message.usage.iterations as advisor_message entries with their own model
and are excluded from the top-level message.usage totals. The parser read
only the top-level totals, so advisor spend was silently dropped and never
attributed to the advisor model.
Emit a separate call per advisor_message iteration priced under the
advisor model, preserve those iterations through entry compaction and the
large-line (>32KB) byte-scanner path, and fold advisor cost into the guard
budget. Bump the claude parser and guard cache versions so existing caches
re-parse and pick up the advisor spend.
* test(guard): pin advisor cost fold in the live budget
The guard's advisor fold in computeSessionUsage had no test; dropping
advisorCost from the line cost left all 30 guard tests green. Pins the
fold (advisor line costs more than the same line without iterations)
and the per-message replace semantics under streaming rewrites.
