feat(agents): add CEO and Founding Engineer agent configurations

Establish multi-agent infrastructure with two initial agent roles:

CEO Agent (agents/ceo/):
- AGENTS.md: Root configuration defining home directory conventions,
  memory system integration (para-memory-files skill), safety rules
- HEARTBEAT.md: Execution checklist covering identity verification,
  local planning review, approval follow-ups, assignment processing,
  delegation patterns, fact extraction, and clean exit protocol
- SOUL.md: Persona definition with strategic posture (P&L ownership,
  action bias, focus protection) and voice/tone guidelines (direct,
  plain language, async-friendly formatting)
- TOOLS.md: Placeholder for tool acquisition notes
- memory/2026-03-05.md: First daily notes with timeline entries and
  observations about environment setup

Founding Engineer Agent (agents/founding-engineer/):
- AGENTS.md: IC-focused configuration for primary code contributor,
  references project CLAUDE.md for toolchain conventions, includes
  quality gate reminders (cargo check/clippy/fmt)

This structure supports the Paperclip-style agent coordination system
where agents have dedicated home directories, memory systems, and
role-specific execution checklists.
