feat: add inline value provider support for mcfunction and Molang documents

[Copilot]

This change adds first-class inline values support to the language server so debug sessions can request variable lookups directly from the server. The implementation introduces the textDocument/inlineValue capability and handles requests for supported Bedrock script languages.

• Capability + handler wiring

  • Added a new InlineValueService in ide/base/server/src/lsp/inline-values/service.ts.
  • Advertises inlineValueProvider during initialization.
  • Registers a connection.languages.inlineValue.on(...) handler.

• Inline value generation

  • Supports mcfunction and molang documents.
  • Scans requested line ranges for variable-like identifiers and emits InlineValueVariableLookup entries.
  • Constrains processing to the requested range / stopped location context and returns empty results for unsupported docs.

• Server integration

  • Wired InlineValueService into setupServer(...) service registration in ide/base/server/src/lsp/server/setup.ts.

onInitialize(capabilities: CapabilityBuilder): void {
  capabilities.set('inlineValueProvider', {
    workDoneProgress: true,
  });
}

setupHandlers(connection: Connection): void {
  this.addDisposable(connection.languages.inlineValue.on(this.onInlineValue.bind(this)));
}
