host 38357c472d feat: per-tier routing activation (v0c)
RoutingPolicy gains tier_modes: a tier entry may be a string
(model, mode inherits global) or {model, mode}. The explicit
tier mode overrides the global mode in both directions, so plan
can be active while goal/default stay shadow, and one tier can
be rolled back to off without touching the others. An invalid
tier mode drops that tier entirely (fail-closed: a typo must
never accidentally activate a tier, and never kills other
tiers). Tier-off tasks return worker_default and are not
audited as policy/shadow, so they never inflate shadow sample
counts. Explicit task and worker-CLI models still win over any
tier mode.

Tests: test_routing_tier.py (5 tests).

"""分档激活 v0c 单测:档模式优先全局、字符串兼容、无效档模式丢档。
运行(在仓库根目录下):
python3 -m unittest discover -s cloud/tests -p "test_routing_tier.py" -v
说明:纯函数单测,不碰库、不联网、不跑模型。关键断言:
全局 shadow 时 plan 档 active 只切 plan 档、其余档仍影子;
全局 active 时某档 off 只回滚该档;档模式写错时该档整档
丢掉、不回落全局(防 typo 误激活),其余档不受影响;
字符串档写法继续按全局模式走。
