chore: bump version to v2.4.0

Bump root and compat package versions (and the compat agora-agents
dependency floor) to v2.4.0, and add the v2.4.0 changelog entry, so the
v2.4.0 release tag passes the publish job's version-match check.

+## [v2.4.0] — 2026-06-30
+
+### Added
+
+- **Area-aware default ASR vendor selection** — The default ASR vendor is now chosen based on the client area, with updated documentation and tests.
+- **New engine API vendors** — Adapted agentkit to the new engine API vendors, with refreshed vendor and regional routing guides.
+
+### Changed
+
+- **Gemini / Vertex LLM configuration** — Aligned Gemini and Vertex LLM config handling; the URL is now always included in Gemini and Vertex LLM configurations, and `project_id`, `location`, and `adc_credentials_string` are passed under `params` in the VertexAI configuration.
+
+### Fixed
+
+- **Avatar configurations** — `SenseTimeAvatar` now treats `sceneList` as optional, and `AnamAvatar` requires `avatar_id` instead of `persona_id`.
