feat: scaffold @imtbl/audience-core package

Add the shared audience core package structure that the web SDK
and pixel will both depend on. Source modules added in follow-up
PRs (SDK-33, SDK-34).

- packages/audience/core/ added to pnpm workspace
- package.json, tsconfig, eslint, jest config matching SDK conventions
- CODEOWNERS updated to @immutable/ped-stream-sdk-integrations-list
- Lockfile updated
