Playground V3: Feature enhancements

[iamramtin]

Once the V2 refactor is complete (#570), would be good to expand the feature-set of playground.

Here are some features I think would be useful:

• Shareable URLs - Encode editor state in URL for easy collaboration
• Session history - Browser-based history of recent playground sessions
• Full Bento config evaluation - Not limited to Bloblang mappings
• Prebuilt examples - Template library showcasing common Bloblang/Bento patterns

Related:

• Full Bento Linter. Could extend the existing Bloblang lint API (HTTP/WASM) to handle full Bento validation/linting. Since Bento config = Bloblang + YAML, this means validating both the mapping logic and YAML structure. Could be integrated into the playground and/or exposed as a standalone API.

Eventually:

• VS Code extension (maybe in V4 lol)

Open to suggestions. What features would make writing Bloblang and Bento configs more useful?

Full Bento config evaluation - Not limited to Bloblang mappings

I like the idea of this 👍

The other stuff too sounds great
