test(acp): record Haiku 5.5 qualification as FAIL

[geeen-jp]

Result

FAIL — Haiku 5.5 High is not qualified. The five bounded live attempts do not preserve same-session and same-turn evidence for the exact served model, effective effort=high, read-only proof, subscription/OAuth without PAYG, and native json_schema acceptance plus schema-valid output. This is missing evidence, not an observed provider incompatibility.

This PR adds generic ACP regression coverage and records the live evidence gap, environment versions, SDK SHA, and validation results. No production source changed because the existing generic Claude path is sufficient and the live evidence does not justify a Haiku-specific branch.

Verification

• Focused ACP tests: 526 passed.
• make validate: passed (SDK 6,162; Agent Server 2,083; Workspace 191; Cross 438; Tools 926; Pyright 0 errors).
• git diff --check: passed.

Closes #69

Haiku routing remains blocked for Scheduler #73 and Workflow OpenHands#362 because this qualification is FAIL.
