v0.10.1

Specification revision 5.1: every pair C review is a binding verdict, one per
tick, and the pair C precheck ships with a working busy guard.

Pair C precheck. The defi-com driver precheck is now versioned beside pair
A's (docs/plans/orca-automations-precheck-c.sh). Two defects are fixed: the
terminal-hygiene/busy block never ran (its guard compared the automation id to
itself), which let a scheduled run launch over a still-working attended run;
and due-work read a cursor shape the driver never writes, so an expired repair
cap could not wake the driver. The hygiene behaviour tests now run over both
drivers and pin the driver-written cursor shape.

Binding verdicts everywhere for C. Automation C has no COMMENT path: a
peer PR reached through the qualifying mention trigger takes a verdict exactly
as an officially-requested one does; an incidental mention stays discovery
data. Pair A/B is unchanged and keeps COMMENT-only.

One verdict per tick. A per-tick review budget of one binding verdict,
oldest updatedAt first, is the brake that replaces the COMMENT-for-mentions
rule. The user may lift it for an attended session; the override is recorded in
the run record. Three caps now: one repair per PR per 24h, six pushes per tick,
one verdict per tick.

Installed skills and the repository match again after this release.
