* feat(llm): add OpenRouter app attribution headers (#339)
Attach EvoScientist app-attribution at the shared model-init layer so all
OpenRouter calls are credited to the project. langchain-openrouter maps
app_url/app_title/app_categories -> HTTP-Referer / X-Title /
X-OpenRouter-Categories. Applied only for the openrouter provider, via
setdefault so explicit caller kwargs win. Configurable through new
openrouter_http_referer / openrouter_app_title / openrouter_app_categories
settings and their EVOSCIENTIST_OPENROUTER_* env vars.
Closes#339
* refactor(llm): centralize OpenRouter attribution defaults + cap categories
Address PR #344 review:
- Define the app-attribution default constants once in config/settings.py
(the config fields and llm/models.py both use them) instead of duplicating
the literals across the two modules.
- Reduce the default categories to creative-writing,personal-agent and cap the
sent list to OpenRouter's 2-per-request limit, warning when a configured list
exceeds it, so extras are dropped predictably (and surfaced) here rather than
being silently truncated server-side.
