Enforce uniform 75% coverage gate across all packages

Replace the observability-only threshold in the grouped test runner with a
uniform 75% gate applied to every package. Drop the observability-specific
--cov flags from pytest addopts since coverage is now enforced per package by
run_tests_by_package.py. Completes coverage-parity-v1.

 **Why:** `llm_observability_analytics` ships with a 75% coverage gate enforced in CI. `llm_knowledge_ingestion` and `llm_dataset_foundry` do not. Today a regression in foundry coverage to 0% would pass CI. The goal of this milestone is to bring all three packages to the same gate and enforce it uniformly.

+enforced for all three packages by the grouped test runner.
 
 | Package | Coverage | Gate | Gap |

 | `llm_observability_analytics` | 80% | 75% (enforced) | — |
-| `llm_knowledge_ingestion` | 76% | none | parsers/base.py at 0% |

+All three packages now clear the gate; coverage-parity-v1 is complete pending
+issue closure. The per-package gaps that motivated this milestone have been
+closed with in-process unit tests for the foundry config/orchestrator/CLI and an
+ingestion CLI test.
