Plugin Directory: Warn about invalid Requires plugin headers on import - #1196
The importer prefers the Requires at least and Requires PHP headers from the main plugin file over the readme, but it only checks that they roughly look like a version ([\d.]{3,}). So a plugin can ship Requires at least: 7.4. The directory stores that silently, and WordPress refuses to activate the plugin. The readme fields get range-checked and dropped with a warning when they’re invalid. The plugin headers can’t simply be dropped, because WordPress enforces them.
The import now adds a warning (shown to the plugin’s committers on the plugin page, like the other import warnings) when:
the Requires at least header isn’t a valid WordPress version, or is newer than trunk, using the same rules as the readme field;
the Requires PHP header isn’t a valid PHP version, using the same rules as the readme field;
either header disagrees with the readme field of the same name, when the readme sets one. 6.0 and 6.0.0 count as the same.
What gets stored doesn’t change: a well-formed header still wins over the readme, since that’s what WordPress enforces.
Testing
Import_Requires_Header_Warnings_Test covers the warning logic.
On a local plugin directory (npm run plugins:env start in environments/), commit a plugin whose main file has Requires at least: 7.4 and whose readme has Requires at least: 6.0. Run the import, then open the plugin page while logged in as a committer, e.g. http://localhost:8888/plugins/<slug>/. The import warnings notice should say the Requires at least header isn’t a valid WordPress version.
Change the header to 6.2 and import again. The notice should now say the header doesn’t match the readme (6.2 vs 6.0).
Make the header match the readme and import again. The notice should go away.
Plugin imports now report warnings when WordPress or PHP requirements in the main plugin file are malformed or differ from the readme.
Warnings also flag WordPress requirements that exceed the supported version.
Validation messages include the supplied value and valid-version examples for malformed requirements. When values differ from the readme, messages show both values and clarify that the main plugin file’s requirement is used.
The importer prefers the Requires at least and Requires PHP headers from the
main plugin file over the readme, but only checks that they look roughly like
a version. A plugin can ship `Requires at least: 7.4` and the directory stores
it without a word, while WordPress refuses to activate the plugin.
The readme fields can simply be ignored when they're invalid; the plugin
headers can't, because WordPress enforces them. So the import now warns the
plugin's committers when a header isn't a valid version, is newer than trunk,
or disagrees with the readme.
Fixes #7781.

The import process now checks plugin-file RequiresWP and RequiresPHP headers. It adds warnings for invalid values and mismatches with readme requirements. The validator translates these warning codes into messages that include relevant values.

Summary
Generate and attach header warnings wordpress.org/public_html/wp-content/plugins/plugin-directory/cli/class-import.php, wordpress.org/public_html/wp-content/plugins/plugin-directory/tests/Import_Requires_Header_Warnings_Test.php
The import checks requirement header formats, WordPress version limits, and mismatches with nonempty readme values. It normalizes trailing .0 segments before comparing values. Tests cover matching, absent, invalid, and mismatched values.
The validator translates invalid-header warnings with version examples. Mismatch messages show the plugin-file and readme values and state that the plugin-file value is used.
At affected version boundaries, a valid readme requirement can be ignored and a mismatch warning missed. Correct the comparison or accept this limited risk before merging.

What changed in this PR
Adds import-time warnings for invalid or inconsistent Requires at least and Requires PHP plugin headers while preserving existing header precedence and storage behavior.
Changes:
Validates plugin requirement headers against WordPress and PHP version rules.
Warns when headers conflict with corresponding readme fields.
Adds translated warning messages and PHPUnit coverage.
`6.8 + 0.1` is 6.8999999999999995 as a float, so on some stable branches a
Requires at least header naming trunk was reported as not a valid version.

- Line 1525: Round the stable-branch-plus-0.1 limit in
readme/class-parser.php::sanitize_requires_version() to match the rounding used
in the import check. Preserve the parser’s existing validation and header
comparison behavior so a requires value of 6.9 is retained when the stable
branch is 6.8.
