📝 export public API option types for typedoc

[thomas-lebeau]

Motivation

The generated typedoc API reference (e.g. DatadogRum.startResource) is missing dedicated pages for several option types passed to public methods — ResourceStopOptions, ResourceOptions, ActionOptions, FeatureOperationOptions, and FailureReason. Parameter types render as bare names with no link, so users can't discover the available fields.

Root cause: typedoc.json excludes packages/rum-core, so any type referenced from RumPublicApi must be re-exported through the rum/rum-slim entry points to get a generated page. These five types weren't.

Changes

• packages/rum-core/src/index.ts — export ActionOptions, ResourceOptions, ResourceStopOptions, FeatureOperationOptions, FailureReason.
• packages/rum/src/entries/main.ts and packages/rum-slim/src/entries/main.ts — re-export the same five types so typedoc resolves them.

No runtime change; pure type re-exports.

Test instructions

Build and serve the docs locally:

yarn serve:docs

Then in the browser, browse to DatadogRum (under both @datadog/browser-rum and @datadog/browser-rum-slim) and click through the parameter types of:

• startResource → ResourceOptions
• stopResource → ResourceStopOptions
• startAction / stopAction → ActionOptions
• startFeatureOperation / succeedFeatureOperation / failFeatureOperation → FeatureOperationOptions
• failFeatureOperation (second arg) → FailureReason

Each should now navigate to its own page describing the available fields, instead of rendering as a non-clickable type name.
