feat: Add StatusMessageWatcher

[Pijukatel]

Description

Add the option to log status and status messages of another Actor run. If such Actor run is also redirecting logs from another Actor run, then those logs can propagate all the way to the top through the StreamedLog - deep redirection. If the Actor run from which we are redirecting status messages is not redirecting logs from its children, then the log and status redirection remains shallow - only from that Actor run.

Example usage:

Actor.call - default

This will redirect logs by default. Example default redirected line:

2025-10-22T13:06:39.476Z redirect-log-tester runId:SoK1VRJxG61tVrgNz -> 2025-10-22T13:06:06.686Z ACTOR: Status: FAILED, Message: Different status message

...
await client.actor('redirect-actor-id').call();

Actor.call - custom Log

This will redirect logs using custom log and logger. Example default redirected line:

2025-10-22T13:06:39.476Z customPrefix 2025-10-22T13:06:06.686Z ACTOR: Status: FAILED, Message: Different status message

...
await client.actor('redirect-actor-id').call(someInputs, {
    log: new Log({ level: LEVELS.DEBUG, prefix: 'customPrefix', logger: new LoggerActorRedirect()
    }),

Actor.call - no log redirection

This will disable all log redirection (same as current behavior)

...
await client.actor('redirect-actor-id').call(someInputs, {log: null}),

Actor.run - attaching to already running actor and redirecting statuses and status messages

A typical use case is redirecting statuses and status messages from an Actor that runs in standby.

...
const statusMessageWatcher = await client.run('redirect-run-id').getStatusMessageWatcher();

statusMessageWatcher.start();
// Do some stuff while also redirecting statuses from another Actor run
await statusMessageWatcher.stop();

Example actor with recursive redirection:

Issues

• Partially implements: .actor().call() method to set the correct timeout, show the progress in status message, and stream logs #632
• Parity PR in Python: feat: Add StatusMessageWatcher apify-client-python#407

Just for testing, revert before merging.

These two constants are for sure up for discussion.
