chore: update tooling and config for v6 prefix #3130

Phase 0.2: Rename tooling and config for v6 prefix

Part of the v6 migration (#3110). Tooling and config need updating so that pf-v6-* elements are recognized, and pf-v5-* exports are removed since the v6 release will not ship v5 elements.

Tasks

• Update eslint.config.js ignore globs — currently hardcoded to pf-v5-icon demo path (line 16), needs to include pf-v6-icon (or generalize)
• Update elements/package.json exports — replace all pf-v5-* export entries with their pf-v6-* equivalents. The v6 release will not contain pf-v5 elements, so these should be updated, not duplicated
• Audit tsconfig paths for any v5-specific entries
• Update web-test-runner.config.js and playwright.config.ts globs if needed
• Verify commitlint.config.js handles both prefixes (currently strips pf-v\d+- dynamically — looks fine already)

Notes

• commitlint.config.js already normalizes scopes dynamically via regex (pf-(?:v\d+-)?), so no changes needed there
• tsconfig, web-test-runner, and playwright configs don't appear to have hardcoded v5 globs currently, but should be verified as elements are ported
• This can be done incrementally as v6 elements land, or as a batch once enough elements exist
