Summary

Implements #923 — custom system prompts with save, switch, and manage templates.

Changes

Settings (src/settings.py)

system_prompt_mode: "default" | "append" | "replace" — controls how custom prompt is applied
custom_system_prompt: inline custom prompt text
saved_prompts: name→content dict of saved prompt templates
active_prompt: name of the currently active saved prompt

Prompt Assembly (src/agent/system_prompt.py)

New _apply_custom_prompt() function applies custom text after the built-in prompt is fully assembled
Active saved prompt takes precedence over inline custom_system_prompt
Graceful fallback: if custom text is empty, built-in prompt is returned unchanged

API Endpoints (routes/settings_routes.py)

GET /api/auth/prompts — list saved prompts, active prompt, and mode
POST /api/auth/prompts — save/update a prompt (body: {name, content})
DELETE /api/auth/prompts/{name} — delete a prompt (auto-deactivates if active)
POST /api/auth/prompts/activate — set active prompt (body: {name} or {name: ""} to deactivate)

Tests (tests/test_custom_prompts.py)

32 tests covering CRUD, activate/deactivate, all 3 modes, prompt assembly, route auth

Test Results

1152 passed (1120 baseline + 32 new), same 9 pre-existing failures
No regressions
