Joe b47eef1173 Add live syncback functionality and optimize service encoding 
- Introduced a new endpoint `/api/syncback` for one-click full sync from Roblox Studio to the filesystem, eliminating the need for an active WebSocket connection.
- Implemented `SyncbackRequest` and `ServiceChunk` structures to handle service-level properties and child instances during syncback.
- Enhanced `encodeService` to include ObjectValue carriers for accurate reference handling and prevent data loss.
- Updated the syncback process to utilize Luau-style relative paths for reference attributes, improving path management and consistency.
- Integrated session caching in the matching algorithm to optimize performance during syncback operations.

These changes significantly improve the live syncback experience, ensuring reliable data synchronization and enhanced performance during development.

Extended numeric literal syntax

Note: this RFC was adapted from an internal proposal that predates RFC process and as such doesn't follow the template precisely

Status: Implemented

Design

This proposal suggests extending Lua number syntax with:

  1. Binary literals: 0b10101010101. The prefix is either '0b' or '0B' (to match Lua's '0x' and '0X'). Followed by at least one 1 or 0.
  2. Number literal separators: 1_034_123. We will allow an arbitrary number and arrangement of underscores in all numeric literals, including hexadecimal and binary. This helps with readability of long numbers.

Both of these features are standard in all modern languages, and can help write readable code.
