fix(primitive-author): annotate tier moves and route package config

- annotate the research Must demoted to hook Should 12; narrow Must 5 note
- extend Must 6 to scripts run via an interpreter -c string
- add a fallback dispatch row and comma-joined --target guidance
- fall back when agentsmd-author is not installed
- add the apm-workflow boundary; pin upstream apm source URL

 - **Description:** Installed apm-cli 0.28.0 source — ground truth for what apm deploys from a hook, instruction or prompt file and what it silently skips or only warns on; each Must/Should traces to the research docs' Authoring checklists or audit-only lists, or to ADR-0029, with tier moves annotated inline, and the `**/*.instructions.md` local-discovery glob behind the template-suffix Gotcha is `primitives/discovery.py` `LOCAL_PRIMITIVE_PATTERNS`; the per-target event rename maps are `integration/hook_integrator.py` `_HOOK_EVENT_MAP`; and Step 4.2's render relies on `apm install <local path>` deploying the working tree to every `--target`, verified against 0.28.0
