feat: add Zyra cognitive analyst skill

[sonoxo]

Adds a public intelligence-tradecraft-inspired operational cognition skill for Zyra.

Adds

• requirements → planning/direction → collection → processing/exploitation → analysis/production → dissemination → reflection cycle
• explicit operational self-model for mission, phase, capabilities, limits, evidence, unknowns, judgments, and strategy history
• source/provenance discipline
• observation vs inference vs hypothesis vs recommendation separation
• assumption checks, alternative analysis, disconfirming-evidence prompts, and uncertainty statements
• bounded retry/change-strategy behavior
• consequential-action evidence/reversibility gates
• bridge to GPT-DOUG-LLM adaptive_intelligence.py and cognitive_analyst_core.py

This is based on public CIA/FBI/ODNI analytic concepts plus the user-provided public EverydaySpy document. It does not claim government affiliation, classified access, sentience, or human consciousness.
