Release-prep bump across the Claude Code, Codex, and Gemini manifests.
Cutting v4.3.0 also fixes#33: gemini extensions install pulls the latest
GitHub release, and gemini-extension.json was added after v4.2.0, so it
was missing from the release tarball. Shipping it in a release fixes the
plain install command.

hooks/hooks.json used ${PLUGIN_ROOT}, which Claude Code never defines, so the literal resolved against the hook process cwd and SessionStart/UserPromptSubmit failed with 'Cannot find module'. Switch to ${CLAUDE_PLUGIN_ROOT} (and %CLAUDE_PLUGIN_ROOT% for the Codex commandWindows variant); Codex aliases CLAUDE_PLUGIN_ROOT so both hosts resolve. Drop the duplicate inline hooks block from .claude-plugin/plugin.json so hooks load from a single canonical source.
