Make it possible to control how many sources to look at

[choskeli]

Is your feature request related to a problem? Please describe.
Sometimes I would like perplexica to do deeper research and check more sources and leverage the entire context window of the large language model I'm using.

Describe the solution you'd like
Perhaps a deep search mode or a control that lets you control how much of the context window to fill up before stopping looking for sources. Instead of searching 12 or so pages it could search 30+.

Describe alternatives you've considered
I've tried you.com research mode but I think perplexica would be even better if it had a similar but even more aggressive mode.

Additional context
We may need to make it clear to the LLM what date each source is from so it prioritizes newer sources.
