fix: update user/relation/object regex validation.

[SyedM-dev]

Update the regex validation for user, relation, and object under CheckRequestTupleKey.

Updated regular expressions used for user, relation and object under CheckRequestTupleKey in the following manner:

• user: ^(?=.{2,512}$)(?:[a-z_-]+:(?:[a-zA-Z0-9_/#-]+|\*))$
• relation: ^[a-z]{1,50}$
• object: ^(?=.{2,256}$)(?:[a-z_-]+:(?:[a-zA-Z0-9_/-]+|\*))$

Description

I tried to follow the docs for this project to ensure the regex matches, if there is a mistake or edge case please correct me. This is also my first code-based PR so please correct me if i did not understand the issue properly.

This PR has had no human activity for 90 days, so it has been marked lifecycle/stale.

This is automated backlog grooming, not a judgment on the work.

What happens next, unless there is activity:

• In 30 days, it will move to lifecycle/closing-soon
• 30 days after that, it will be closed

To keep it open, push a commit or leave a comment, and the clock will reset. For work that should not auto-close, such as an RFC or long-running experiment, ask a maintainer to add lifecycle/frozen.

[curfew-marathon]

This PR has had no human activity for 30 days since being marked lifecycle/stale, so it has now been marked lifecycle/closing-soon.

It will be closed in 30 days unless there is new activity.

If the work still matters, this is the moment to say so: leave a comment, push a commit, or ask a maintainer to add lifecycle/frozen if it should be kept open long-term.

If this work is no longer being pursued, no action is needed.
