rcourtman a343ba0126 Tier patrol-coverage health impact by recent-error ratio
The overall health score chip read "A · 95/100" while the same
assessment card said "Coverage incomplete · Recent Patrol runs
encountered errors · Verify full coverage." Those messages
contradicted because the "recent errors but had a successful run"
coverage factor used a flat -10 penalty regardless of the error
ratio. With one successful manual run among many failed startup
runs, the math stayed in the A band and the score directly
undermined the warning it sat next to.

The factor now tiers the impact by ratio of errored runs to
relevant runs in the scoring window:

  >50% errored → -30, "Most recent Patrol runs encountered errors
                       (N of M); the current health summary is not
                       reliable until coverage stabilizes."
  >25% errored → -20, "Recent Patrol runs encountered errors
                       (N of M), so the current health summary
                       may be incomplete."
  else         → -10, original light-tier description.

A single transient error stays in grade A; dominant-error periods
drop out of A so the grade matches the warning. Adds two tests
covering both ends of the new tiering and updates the ai-runtime
subsystem contract Current State section.
