Add pluggable phonemizer (JA/EN/RU/Raw) and easier entry renaming

[MysticILD]

Adds a phonemizer to the rename-entry dialog. Supports Raw, Japanese (kana/romaji), English (CMUdict + ONNX fallback + rule-based) and Russian (dict + ONNX + rule-based) via a PhonemizerPlugin registry. The dialog can phonemize input and spread the result across multiple entries (Tab/Shift-Tab). Dictionaries/models under src/jvmMain/resources/g2p/ and onnxruntime are bundled; string keys added for the UI.

Hello, thanks for the PR.
I feel that it might be too much change for this feature. Adding a new customizable layer is a lot. Is it possible to do it via the plugin system?

[MysticILD]

Hello, thanks for reviewing! Yes, the JA/EN/RU PhonemizerPlugins can be implemented as Type.Macro plugins (resourceFiles = dict.txt/phones.txt, phonemize(text) -> renameMultipleEntries). That would move the dict/rule-based logic out of src/jvmMain/resources/g2p/ into 4 bundled macro plugins (However, OnnxG2pPredictor will be needed to kept in core since GraalJS lacks an ONNX runtime). I also propose keeping the Tab/Shift-Tab navigation in EditEntryNameDialog as it's generally useful for batch renaming entries. If that sounds good I'll rewrite the PR to that approach.

Hello, I've updated the PR based on your feedback:

• Moved phonemizers into the plugin system as Plugin.Type.Phonemizer (under resources/common/plugins/phonemizer/ with standard plugin.json), dropping the extra custom phonemizer folder and loader layer entirely.
• Kept G2P support generic in core. The .onnx models, dicts, and phone tables now live in their respective plugin folders, and JS can call g2p.predict(modelFile, graphemes, phonemes, word) through an injected bridge so any phonemizer plugin can use ONNX models.
• Kept the rename dialog workflow (inline toggle, preview chips, multi-entry spreading), and made Tab / Shift-Tab remappable in Preferences > Keymap (KeyAction.EditEntryNameDialogNext/Previous).

Let me know what you think!

@MysticILD can we use the macro plugin system? I don't think phonemizer is a core feature that a labelling app needs to have. Besides, we support customizable plugins, so we don't really need to commit the plugins into this repo, you can publish your plugins anywhere. I'm saying this because I don't really want to add embedded binaries or resources from other projects with an extra license.

Hello, sorry for the late reply!
Yeah, that makes sense. I still think having the ability to quickly cycle through and edit entry names with Tab and Shift+Tab is a nice QoL feature to have in core, though. If that's okay with you, I can strip down this PR so it just adds the next/previous entry shortcuts for the rename dialog.
