Dylan/feat/reducers editor tool

About

GUI Reducer listing/calling with prefilled with the CLI-default server/identity (and module name, if cached from previously using the other "Publisher" tool).

Why?

With the Publisher tool, we took away numerous CLI burdens and tossed it into a GUI with persistence to remember your prefs.

The effort continues! Less CLI burdens, more GUI, easier onboarding/reducer testing.

Prerequisites

Branched from https://github.com/clockworklabs/com.clockworklabs.spacetimedbsdk/pull/17 - resolve this PR 1st

Feats

• Get default selected server/identity from CLI and load it into UI @ init

• Get last-published module Name and load it into a TreeView UI @ init, if any

• Parses spacetime describe into a model

• Parses describe into an EntityInfo model with extra info, such as [formatted] syntax hints and more

• Refresh button, in case we changed something after init

• "Call Reducer" button for reducers with results shown below

• UX: Local validation, btn enable/disables on ready/done, progressive UI reveal, btn status labels on click, window wrapped in ScrollView, result labels wrapped in ScrollView (in case of lengthy errs), can dock to editor UI as a tab

• Minor Publish optimizations (since closely related and templated from)

  • Some fixes, some tweaks, some consistency.
  • Centralized some common elements back to /Common
  • EDIT: --as-identity support

• Err handling:

  • Implicit #VisualElement name integrity
  • Refer to Publisher tool on server<>identity errs

⚙️ Editor tool only: This won't bloat builds. ⚙️ Tested in Unity 2022.3.20 LTS

Ideas for future PRs:

1. From Reducer window, have an "Open Publisher Tool" button on identity/server err
2. From Publisher window, have an "Open Reducers Tool" button on Publish success in the Result Foldout.
3. Since we parse the entire spacetime describe into a common model, there are likely other fun tools to be made from this.
4. TreeView supports sub elements, if we ever wanted to do something "extra" with a selected reducer, such as describing what each arg does (if we ever add arg docs within spacetime describe results, for example).
5. Caching last known set of reducers (but can cause confusion on desyncs).

Testing

• Tested via Zeke's demo project, which includes pretty much everything- including custom types and deep nested.
• Currently showing premade funcs like Init; unsure what to do with these:

TODO

• Add this tool to the README with a GIF
• Wrap short if() with if(){} (I learned this internal pref later)
• Emulation support as a player ("bot").
  • Eg: Let's say I want to call the tutorial's chat_message - I get an err response "Player not found"
