feat: add ForgeBridgeServer named pipe IPC for live skybox updates

[TimMasalme]

Summary

Adds ForgeBridgeServer.cs, a MonoBehaviour that opens a named pipe
(ForgeMapToolkit.EditorBridge) and receives live skybox snapshots from
ForgeMapToolkit, applying them instantly in the editor without manual
export/import.

How it works

• Background thread runs an accept loop; each connection starts a
  length-prefixed read loop (4-byte LE uint32 + UTF-8 JSON body, 1 MB cap)
• On connect, a handshake verifies that the Toolkit's mapName matches
  MapLuaParser.Current.FolderName — responds with handshake.response
  and optional map.mismatch
• Valid skybox.snapshot messages are queued (ConcurrentQueue) and
  drained on the Unity main thread in Update() via ApplyPatch(),
  which writes into AdditionalSkyboxData.Data and calls LoadSkybox()
• Accept loop reopens the pipe after each disconnect — no Editor restart
  needed

Setup / Build notes

1. ForgeBridgeServer is attached to the OzoneMapEditor GameObject in
   the MapEditor scene (included in Assets/MapEditor.unity)
2. Run In Background must be enabled — set in Project Settings → Player
   → Resolution and Presentation. Without this, Update() is throttled
   when the Editor window loses focus and live updates stall.
   This change is included in ProjectSettings/ProjectSettings.asset.

Notes

• The original design called for a PipeSecurity ACL restricting pipe
  access to the current Windows user. Unity's Mono runtime throws
  NotImplementedException on that constructor overload at runtime, so
  the basic constructor is used instead. Both ends run under the same
  local user session, so this is acceptable.
• This is the Editor-side companion to editor-bridge.js in the
  ForgeMapToolkit repo (currently private-repo)

Warning

Review limit reached

@TimMasalme, we couldn't start this review because you've reached your PR review rate limit.

More reviews will be available in 37 minutes and 36 seconds. Learn how PR review limits work.

Your organization has used up its prepaid credits, and credit purchases are no longer available. Enable the review add-on in the billing tab to keep reviews running — you're only billed for reviews past your plan's rate limits ($0.25/file).

⌛ How to resolve this issue?

After more reviews become available, a review can be triggered using the @coderabbitai review command as a PR comment. Alternatively, push new commits to this PR.

To avoid repeated limits, reduce automatic review volume by pausing incremental auto-reviews earlier, using label-based review opt-in, excluding WIP or generated PR titles, or requesting reviews manually when the PR is ready. If your team needs uninterrupted high-volume reviews, an organization admin can enable usage-based credits.

🚦 How do rate limits work?

CodeRabbit enforces per-developer PR review limits for each organization. Most developers receive the normal plan refill rate.

For paid Pro and Pro+ PR reviews, CodeRabbit uses adaptive limits for sustained high-volume activity. When a developer's recent PR review activity reaches the 95th percentile or higher among CodeRabbit users, the refill rate gradually slows as usage increases. The highest same-day bursts are limited more strictly.

Please see our Fair Usage Limits Policy for further information.
