prompts.py

"""Unified prompt registry for all agent roles.

Consolidates the previously separate SUB_AGENT_PROMPTS (legacy round-based system)
and SPECIALIST_PROMPTS (DAG-based system) into a single registry with clear
lookup semantics.

Lookup order in ``get_prompt(role, mode)``:
    1. PROMPT_REGISTRY[role]  (specialist / DAG prompt if available)
    2. Fallback to "backend_developer" as default

The ``{agent_mode_prompt}`` placeholder is replaced with the execution-mode
snippet at lookup time.
