Commit Message

feat(dpc,opc): support bypass_cache directive with allow_query_cache_bypass guard

Support bypass_cache=1 or hard_refresh=1 query parameters, form values,
X-Bypass-Cache header, and PromQL # bypass_cache statement directives.
To prevent uncontrolled resource consumption (DoS/cache stampede),
this capability is guarded by the backend option allow_query_cache_bypass
(disabled by default).

When enabled and detected, Trickster safely purges the tainted cache
entry from the cache store, fetches fresh data from origin, and serves
the full untruncated dataset to clients.
