Add Keyword Auto Read extension

[hyprninja]

Adds Keyword Auto Read to repositories.json and the README list.

It marks incoming articles as read when they match a keyword rule, so they never reach the unread stream. FreshRSS already does this per feed through filter actions; this applies one rule set across every feed.

• Hooks entry_before_insert; rules can be plain keywords, scoped to a single field (title:, content:, author:, url:, tag:) or full PCRE, with whole-word and case-sensitivity options
• Feed include/exclude lists, a dry-run mode that only logs, and an in-page tester for checking a rule against a sample headline
• An optional sweep that applies the rules to articles already stored, paging through FreshRSS_EntryDAO::listWhere() under a time budget; it only ever marks read, never deletes

Written against the 1.29.1 sources. metadata.json carries name, author, description, version, entrypoint and type, and the extension lives in xExtension-KeywordAutoRead/ at the repository root, so generate.php should pick it up. Licensed AGPL-3.0.

The repository has a standalone test harness (no FreshRSS or composer needed) that stubs the FreshRSS API, run in CI with php -l on every source file across PHP 7.4 to 8.4.

And for all feeds, if you put the search filters for auto mark as read in Configuration > Reading > Filter actions.

See https://freshrss.github.io/FreshRSS/en/users/10_filter.html#with-the-search-field for the syntax.
