[bennypowers]

Summary

Rename <pf-table> to <pf-v5-table> and update associated CSS custom properties to use the pf-v5 prefix.

Scope

• Rename element tag from pf-table to pf-v5-table
• Rename all CSS custom properties (e.g. --pf-table--* to --pf-v5-table--*)
• Update internal class names, imports, and type declarations

Sub-components

Also rename:

• <pf-caption> to <pf-v5-caption>
• <pf-tbody> to <pf-v5-tbody>
• <pf-td> to <pf-v5-td>
• <pf-th> to <pf-v5-th>
• <pf-thead> to <pf-v5-thead>
• <pf-tr> to <pf-v5-tr>

Requirements

• MUST maintain feature parity with the current <pf-table> implementation
• MUST rename all public CSS custom properties
• MUST update HTMLElementTagNameMap declarations
• SHOULD provide a codemod or migration guide for downstream consumers
