Add --hook flag to validate WordPress hook execution before shell starts

[Copilot]

Users need to validate that specific WordPress hooks have fired before running shell commands for QA workflows where code execution depends on preconditions being met (e.g., plugins loaded, init completed).

Changes

Shell Command

• Added --hook=<hook> parameter to wp shell command
• Validates hook has fired via did_action() before starting REPL
• Returns error with available hooks list if hook hasn't fired yet

Example Usage

# Ensure init hook has fired before starting shell
$ wp shell --hook=init
wp> // Shell starts with full init context

# Error if hook not yet fired
$ wp shell --hook=shutdown
Error: The 'shutdown' hook has not fired yet. The shell command runs after WordPress is loaded, so only hooks that have already been triggered can be used. Common hooks that are available include: init, plugins_loaded, wp_loaded.

Tests

• Hook validation with init and plugins_loaded
• Error handling for unfired hooks

Scope

This implements the feature for wp shell only. The issue also mentions wp eval and wp eval-file, but those commands are in the separate wp-cli/eval-command repository.

Limitations

Only hooks that have already fired when the command runs can be validated. WP-CLI commands execute synchronously after WordPress loads, so most core hooks (init, plugins_loaded, wp_loaded) are available. Waiting for future hooks is architecturally infeasible.

<issue_title>Add --hook=<hook> flag to eval and shell to choose timing</issue_title>
<issue_description>## Feature Request

For both the eval|eval-file commands as well as the shell command, there's a fixed point in time within the WordPress lifecycle that these are executed.

It would be great to have a --hook=<hook> flag for these that allows the user to postpone when they are being triggered, so that you can choose a specific time within the WordPress lifecycle to run them on.

• Yes, I reviewed the contribution guidelines.

Describe your use case and the problem you are facing

An example is using these commands to QA new code. Some code can only be executed once the preconditions are met, which means they need to be executed at or after a certain action.

Allowing these commands to be attached to a specific action/filter allows the user to choose when to execute them, so that they can ensure the preconditions for the code to be run are met.

Describe the solution you'd like

This can probably be done by dynamically creating a closure with the code to evaluate or the PsySh breakpoint and attaching that closure to the requested action, instead of immediately executing something.</issue_description>
