feat(cli): add automatic-generate-keys command and improve key generation UX

- Introduced  command to partner-chains-cli:
  - Generates and saves session keys by connecting to a running node via RPC ()
  - Decodes session keys using the runtime API, supports modern and legacy formats, and saves to keystore and JSON
  - Provides fallback and error handling for various runtime formats
- Integrated the new command into the CLI as an alternative to  for all roles (Governance Authority, Registered Validator, Permissioned Validator)
- Updated CLI help message and workflow documentation to clearly present both key generation methods and when to use each
- Added comprehensive test suite for SCALE decoding and key handling logic
- Updated changelog with details of the new feature and related improvements
- Updated Cargo.toml and workspace dependencies for ,  (with serde), and related requirements

 # Unreleased
 
+## Added
+
+* New `automatic-generate-keys` command in `partner-chains-cli`:
+  * Allows users to generate and save session keys by connecting to a running node via RPC (`author_rotateKeys`).
+  * Decodes session keys using the runtime API and saves them to the keystore and `partner-chains-public-keys.json`.
+  * Provides fallback and error handling for various runtime formats.
+  * Fully integrated into the CLI as an alternative to `generate-keys` for all roles (Governance Authority, Registered Validator, Permissioned Validator).
+  * Comprehensive test suite for SCALE decoding and key handling logic.
+  * Help message and workflow documentation updated to show both key generation methods and when to use each.
+
 ## Changed
 
 * Switched from `polkadot-stable2503-07` to `polkadot-stable2506`. `type RuntimeEvent` became deprecated in polkadot-sdk. It has been removed from the toolkit crates. To update to this version of PC toolkit, please remove definition of `type RuntimeEvent` when wiring in runtime.
