chore: remove Samuel, reduce per-heartbeat token load

- Remove Samuel Stinkpost (terminated) from all files and delete marketing/samuel/
- Update PEM listing in OPERATIONS.md to the 4 role-based keys
- POLICIES.md and TOOLS.md are now conditional reads (only when agents have work to do), not loaded on every heartbeat
- Split product/SOUL.md: core identity stays in SOUL.md, reference material (plugin portfolio, competitive landscape, evaluation framework, spec template) moved to PRODUCT-CONTEXT.md
- CLAUDE.md improvements: add OPERATIONS.md/POLICIES.md/TOOLS.md references, fix adapter list, add PR workflow, document opencode.json purpose
