Update _quota_allows_cloud() to use select_model("high") instead of
should_use_cloud(), so the cascade router uses the same metabolic tier
logic as the standalone quota API:
- BURST tier (5h < 50%): cloud providers allowed
- ACTIVE tier (5h >= 50%): cloud providers skipped, local 14B used
- RESTING tier (7d >= 80%): cloud providers skipped, local 8B used
Adds log message showing tier name and suggested local model when
downshifting, so Alexander can verify the protocol is working.
Adds TestMetabolicProtocol test class (5 tests) covering:
- BURST tier allows cloud
- ACTIVE tier skips cloud
- RESTING tier skips cloud
- Local (ollama) providers always attempted regardless of quota
- No quota monitor → cloud allowed (graceful degradation)
Files src/infrastructure/claude_quota.py and scripts/claude_quota_check.sh
were already in place from prior work.
Fixes#1106
