Mission Run Overview
Mission Run: Relocate Built-In Doctrine to packs/built-in
Move built-in doctrine artefacts out of src/doctrine into packs/built-in and load them through the same pack path org and project packs use, so all three tiers are uniform.
Today the shipped built-in doctrine content (agent profiles, directives, procedures, tactics, paradigms, styleguides, toolguides, assets, glossary packs, the DRG graph fragments, schemas, and mission templates) lives inside src/doctrine and is loaded by a different code path than the org and project packs it later composes with. This mission relocates that content to a top-level packs/built-in directory and routes it through the same pack-loading path org and project packs already use, making built-in the uniform base tier of the built-in -> org -> project mechanism. It improves pack authoring and overlay consistency and draws the consumer seam for the open-core delivery window, without extracting the doctrine code itself.
