Adds a persisted, runtime-editable system prompt. The brain reads the persona on every turn (prompt_store.get_persona), so a dashboard edit applies to the next reply with no restart; blank clears the override back to the built-in PERSONA. New endpoints GET/POST /api/prompt, and a reusable modal popup (뒤로가기 + 수정/저장) that later white/blacklist features will share. Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>

"""Persisted, live-editable bot persona (the brain's system prompt).
|
|
|
|
The dashboard lets the user view and edit the bot's system prompt at runtime.
|
|
The brain reads the current persona on every turn, so an edit takes effect on
|
|
the next reply with no restart. The text is persisted to disk so it survives a
|
|
restart; when no override file exists the caller's default
|
|
(``ClaudeBrain.PERSONA``) is used.
|
|
|
|
Path: ``$WSAI_PROMPT_PATH`` or ``~/.config/wsai/persona.txt`` (disk, never a
|
|
RAM-backed tmpfs).
