Add `wp profile requests` command to monitor HTTP requests

[Copilot]

Implements wp profile requests to display all HTTP requests made during WordPress load, showing method, URL, status code, and execution time for each request.

Changes

Command.php

• Added requests() method with standard profiling options (--url, --fields, --format, --order, --orderby)
• Displays fields: method, url, status, time

Profiler.php

• Added $request_start_time and $request_args properties to track individual requests
• Enhanced wp_request_begin() to capture request details (URL, method) when type='request'
• Enhanced wp_request_end() to create Logger entries with timing and status from response
• Updated hook parameters to match WordPress signatures ($preempt, $parsed_args, $url for pre_http_request; $response, $context, $class, $parsed_args, $url for http_api_debug)
• Skip 'all' hook registration when profiling requests to avoid overhead
• Added proper null checks for $parsed_args to prevent PHP warnings
• Reset tracking properties at the start of each request to handle preempted requests (where pre_http_request filter returns early and http_api_debug doesn't fire)

composer.json

• Registered profile requests command

Tests

• Added features/profile-requests.feature with test scenarios including a mu-plugin that makes HTTP requests with HTTP response mocking to prevent actual external requests
• Updated features/profile.feature usage output

Example

$ wp profile requests --fields=method,url,status,time
+-----------+----------------------------+--------+---------+
| method    | url                        | status | time    |
+-----------+----------------------------+--------+---------+
| GET       | https://api.example.com    | 200    | 0.2341s |
| POST      | https://api.example.com    | 201    | 0.1653s |
+-----------+----------------------------+--------+---------+
| total (2) |                            |        | 0.3994s |
+-----------+----------------------------+--------+---------+

Comments on the Issue (you are @copilot in this section)

@danielbachhuber The idea is to create a `wp profile requests` command that would minor execution time, etc. for all HTTP requests made during the WordPress load process.

Here's where we're already hooking into the HTTP request process to observe timing:
