feat: add connection config support

[azeam1]

Note

Medium Risk
Major additive WIT/API change around auth connection config, but older connectors remain supported and this gem only extracts/validates declarative JSON rather than running OAuth flows.

Overview
Bumps to 5.0.0 and adds WIT v5 so connectors can export embedded connection-config JSON through a new connections interface. Older WIT versions keep working; v5 is tried first on load.

App#connection_config reads that JSON and validates it with ConnectionConfigValidator against the new schema (OAuth2, API key, session, runtime headers/templates, post-connect hooks). connections_supported? reports whether the loaded component has the interface.

Also adds a v5 fixture connector, schema docs, and json_schemer as a gem dependency.

Pull request overview

This PR bumps app_bridge to 5.0.0 and introduces WIT v5 (standout:app@5.0.0) with a new exported connections interface so components can embed and expose a validated connection-config JSON document to the Ruby API.

Changes:

• Add Ruby-side connections_supported? / connection_config API, including JSON Schema validation via AppBridge::ConnectionConfigValidator + new ConnectionConfigError.
• Add WIT v5 bindings + loader order update (try v5 first) and wire v5 into the Rust host implementations (http/file/env).
• Add schema/docs/tests and a new v5 Rust WASM fixture + build task updates.

Symbol keys break config validation

Medium Severity

parse_data returns a Ruby Hash unchanged, so symbol keys never match the string keys in the JSON Schema. json_schemer checks required properties with key set difference, so idiomatic symbol-keyed hashes (including the new validator specs and the documented CI-without-WASM path) fail validation even when the config is valid. The WASM string path is unaffected because JSON.parse yields string keys.
