fix(audit): reject retired aliases; sweep gpu-light/gemma-4-12b to gpu-vision

audit-hermes-config.py Rule 8 required auxiliary.vision.model and
auxiliary.web_extract.model to equal the retired 'gpu-light', so a config
adopting the live canonical 'gpu-vision' FAILED our own audit - the audit was
enforcing a dead alias (400 Invalid model name). Rule 8 now requires
gpu-vision; retired names gpu-light/crew-auto join the raw-name rejection set;
the guidance message names the live aliases.

Sweep of the remaining references: gpu-self-heal stops canonicalizing
gpu-light; hermes-config-template, hermes-agent-baseline, hermes-key-enforcement,
inference-optimization, litellm-client-timeouts and gpu-fleet now use the live
gpu-vision alias. Where a file restated model/rpm/weight/fallback state it now
points at CT 116 /opt/inference-harness/litellm_config.yaml instead of
duplicating it. koby's .129 config is report-only and recorded, not edited.

Adds tests/test_audit_hermes_config_alias.py: executes the audit CLI and asserts
gpu-vision passes while gpu-light and gemma-4-12b fail.
