Release/1.4.3 rc1

[gin0115]

Changes proposed in this Pull Request

This pull request prepares for the 1.4.3-RC1 release and introduces several documentation improvements and clarifications, especially regarding how the plugin handles links that block automated checkers (false positives). It also documents a new built-in exclusion list for domains known to block bots, and clarifies the behavior of various options and filters. No code logic changes are included—these are documentation and metadata updates.

Key documentation and metadata changes:

Release and versioning updates:

• Updated version numbers and stable tags to 1.4.3-RC1 in README.md, readme.txt, and internet-archive-wayback-machine-link-fixer.php for the release candidate. [1] [2] [3] [4] [5]

False positives and exclusions:

• Added a new section on "Handling False Positives" explaining why some links may be wrongly reported as broken and how to address this using link exclusions or wildcard rules. [1] [2]
• Documented the new built-in (global) exclusion list for domains known to block automated link checkers, clarifying that these are never checked or archived and cannot be overridden from the UI.
• Clarified the "Link Exclusion" toggle in link reports, including its interaction with user and built-in exclusions.
• Added references to the false positives documentation in relevant sections, such as the Fixer Option and troubleshooting. [1] [2]

Option and filter clarifications:

• Improved descriptions for the Fixer Option, Link Icon, and relevant filters to match the current plugin behavior and terminology, especially regarding when icons and HTML output are shown. [1] [2] [3]

Changelog:

• Added a changelog entry for version 1.4.3 summarizing the global exclusion feature and the reintroduction of a "scan but do nothing" outcome for broken links.

🔱 Poseidon Review

Summary — Documentation and version-bump PR for the 1.4.3-RC1 release candidate; low risk overall, but one version string has a typo that affects what WordPress.org will serve.

• ✨ New — Adds "Handling False Positives", "Built-in Exclusion List", and "Link Exclusion" documentation sections.
• 📝 Docs — Refreshes Fixer Option, Link Icon, and filter descriptions to match current behavior/terminology.
• 🔧 Chore — Bumps version to 1.4.3-RC1, adds a 1.4.3 changelog entry, and gitignores .claude/settings.json.

🔴 Major issues

• readme.txt:L6 — Stable tag: 1.4.3.-RC1 has a stray period; every other version string in this PR reads 1.4.3-RC1. WordPress.org treats the Stable tag field as authoritative for which version SVN serves, so a mismatched tag can deliver the wrong version or break the release. Fix: Stable tag: 1.4.3-RC1.

Major issues:
In `readme.txt`:
- Line 6: The `Stable tag` header currently reads
  `Stable tag: 1.4.3.-RC1`, which contains a stray period
  between `1.4.3` and `-RC1`; this mismatches the `1.4.3-RC1`
  value used in README.md, the `IAWMLF_VERSION` constant, the
  plugin header `Version:` field, and the `@version` docblock.
  On WordPress.org the `Stable tag` field determines which
  version SVN serves to users, so a malformed tag that does
  not match the tagged release can deliver the wrong version
  or break the deploy. Correct the value to
  `Stable tag: 1.4.3-RC1` by removing the extra dot; leave the
  surrounding header lines (Requires at least, Tested up to,
  Requires PHP) unchanged.
