[FEATURE] Display tags consistently in note hover and detail views

[mors119]

Summary

Improve tag visibility in VS Code hover, note details, and sidebar entries.

Tags are currently easy to overlook even when they are stored on a note. They should be visible wherever users inspect note metadata.

Requirements

• Display tags in editor hover content.
• Display tags in note detail or edit views.
• Display tags in sidebar note entries where space allows.
• Use a consistent format across all extension surfaces.
• Avoid overwhelming the hover when a note has many tags.
• Truncate or wrap tags gracefully.
• Escape Markdown-sensitive tag text correctly.
• Keep tags clickable where supported, opening a tag-filtered result view.

Acceptance Criteria

• Tagged notes show their tags in editor hover.
• Note detail and edit views show the same tag values.
• Tag rendering is consistent across views.
• Long tag lists remain readable.
• Clicking a tag opens tag-filtered notes where the UI supports it.
• Untagged notes do not show an empty visual section.

Design Principle

Metadata should be visible at the moment it helps users understand and navigate a note.
