FEATURE: Share conversations with AI via a URL (#521)
This allows users to share a static page of an AI conversation with
the rest of the world.

By default this feature is disabled, it is enabled by turning on
ai_bot_allow_public_sharing via site settings

Precautions are taken when sharing

1. We make a carbonite copy
2. We minimize work generating page
3. We limit to 100 interactions
4. Many security checks - including disallowing if there is a mix
of users in the PM.

* Bonus commit, large PRs like this PR did not work with github tool
large objects would destroy context

FEATURE: AI Quick Semantic Search (#501)
This PR adds AI semantic search to the search pop available on every page.

It depends on several new and optional settings, like per post embeddings and a reranker model, so this is an experimental endeavour.

FIX: Improve AI persona editor inputs and optional GitHub auth (#518)
1. Fix input fields in AI persona editor and make GitHub tool authentication optional

2. AI persona editor improvements and tool GitHub access token check

This pull request makes a few improvements:

- Adds `lang="en"` to number input fields in the AI persona editor to prevent localization issues 
- Adds `step="any"` to allow fractional values for temperature and top_p settings
- Makes GitHub tool authentication contingent on `ai_bot_github_access_token` site setting being present

FEATURE: mentionable personas and random picker tool, context limits (#466)
1. Personas are now optionally mentionable, meaning that you can mention them either from public topics or PMs
       - Mentioning from PMs helps "switch" persona mid conversation, meaning if you want to look up sites setting you can invoke the site setting bot, or if you want to generate an image you can invoke dall e
        - Mentioning outside of PMs allows you to inject a bot reply in a topic trivially
     - We also add the support for max_context_posts this allow you to limit the amount of context you feed in, which can help control costs

2. Add support for a "random picker" tool that can be used to pick random numbers 

3. Clean up routing ai_personas -> ai-personas

4. Add Max Context Posts so users can control how much history a persona can consume (this is important for mentionable personas)

FEATURE: allow personas to supply top_p and temperature params (#459)
* FEATURE: allow personas to supply top_p and temperature params

Code assistance generally are more focused at a lower temperature
This amends it so SQL Helper runs at 0.2 temperature vs the more
common default across LLMs of 1.0.

Reduced temperature leads to more focused, concise and predictable
answers for the SQL Helper

* fix tests

* This is not perfect, but far better than what we do today

Instead of fishing for

1. Draft sequence
2. Draft body

We skip (2), this means the composer "only" needs 1 http request to
open, we also want to eliminate (1) but it is a bit of a trickier
core change, may figure out how to pull it off (defer it to first draft save)

Value of bot drafts < value of opening bot conversations really fast

FEATURE: smooth streaming of AI responses on the client (#413)
This PR introduces 3 things:

1. Fake bot that can be used on local so you can test LLMs, to enable on dev use:

SiteSetting.ai_bot_enabled_chat_bots = "fake"

2. More elegant smooth streaming of progress on LLM completion

This leans on JavaScript to buffer and trickle llm results through. It also amends it so the progress dot is much 
more consistently rendered

3. It fixes the Claude dialect 

Claude needs newlines **exactly** at the right spot, amended so it is happy

It also corrects the syntax around tool support, which was wrong.

FEATURE: scale up result count for search depending on model (#346)
We were limiting to 20 results unconditionally cause we had to make
sure search always fit in an 8k context window.

Models such as GPT 3.5 Turbo (16k) and GPT 4 Turbo / Claude 2.1 (over 150k)
allow us to return a lot more results.

This means we have a much richer understanding cause context is far
larger.

This also allows a persona to tweak this number, in some cases admin
may want to be conservative and save on tokens by limiting results

This also tweaks the `limit` param which GPT-4 liked to set to tell
model only to use it when it needs to (and describes default behavior)

FEATURE: UI to update ai personas on admin page (#290)
Introduces a UI to manage customizable personas (admin only feature)

Part of the change was some extensive internal refactoring:

- AIBot now has a persona set in the constructor, once set it never changes
- Command now takes in bot as a constructor param, so it has the correct persona and is not generating AIBot objects on the fly
- Added a .prettierignore file, due to the way ALE is configured in nvim it is a pre-req for prettier to work
- Adds a bunch of validations on the AIPersona model, system personas (artist/creative etc...) are all seeded. We now ensure
- name uniqueness, and only allow certain properties to be touched for system personas.
- (JS note) the client side design takes advantage of nested routes, the parent route for personas gets all the personas via this.store.findAll("ai-persona") then child routes simply reach into this model to find a particular persona.
- (JS note) data is sideloaded into the ai-persona model the meta property supplied from the controller, resultSetMeta
- This removes ai_bot_enabled_personas and ai_bot_enabled_chat_commands, both should be controlled from the UI on a per persona basis
- Fixes a long standing bug in token accounting ... we were doing to_json.length instead of to_json.to_s.length
- Amended it so {commands} are always inserted at the end unconditionally, no need to add it to the template of the system message as it just confuses things
- Adds a concept of required_commands to stock personas, these are commands that must be configured for this stock persona to show up.
- Refactored tests so we stop requiring inference_stubs, it was very confusing to need it, added to plugin.rb for now which at least is clearer
- Migrates the persona selector to gjs
