[epic] Port v5 elements to v6

Start with the Phase 0 infrastructure issues, especially tools/pfe-tools/dev-server/, eslint.config.js, commitlint.config.js, elements/package.json, and the test configuration files. Review the ordered dependency tiers and linked issues before choosing a scoped PR. Done means the v6 migration plan is completed in order and every PR targets staging/pfv6 rather than main.

PatternFly Elements v6 Migration Plan

Ordered PR plan for issue #3110. UPDATE PRs first (rename existing v5 elements
to v6 and port APIs), then CREATE PRs (new elements not in v5).

CRITICAL: All PRs MUST target staging/pfv6 branch, NOT main

Phase 0: Infrastructure (do first)

These PRs unblock everything else.

PR 0.1: Remove/replace dev server with cem serve (#3102)

• Issue #3110 calls out hardcoded tag names in dev server
• cem serve handles import maps, CSS transforms, chromeless testing
• Remove tools/pfe-tools/dev-server/ and wire up cem serve
• Update npm run dev / npm start scripts

PR 0.2: Rename tooling and config for v6 prefix (#3130)

• Update eslint.config.js ignore globs (icon demo path) to include pf-v6 as
  well as pf-v5 paths
• Update commitlint.config.js to handle pf- prefix (no v5)
• Audit elements/package.json exports for orphaned entries
• Update tsconfig paths if needed
• Update web-test-runner.config.js and playwright.config.ts globs

Keep v5 prefix until all elements are updated.

PR 0.3: Update docs scaffolding (#3131)

• Update docs/_snippets/ for v6 element names
• Update docs/framework-integration/ examples
• Update docs/components/ templates

Phase 1: UPDATE PRs (rename v5 -> v6, port to v6 API)

Existing v5 elements renamed to pf-v6-{name} and updated to v6 PatternFly
design tokens, CSS, and React API parity. Order by dependency graph:
leaf components first, then composites.

Tier 1: Zero-dependency leaf elements

These elements don't depend on other PF elements. Port first.

Checklist for v6 rename (beyond element source files):

Dev Server

[!important]
NB: likely remove dev server altogether in favour of cem serve

• tools/pfe-tools/dev-server/plugins/templates/index.html - element tag names hardcoded in shell UI (nav button, card). Update alongside rename.
• tools/pfe-tools/dev-server/bundle.ts - icon export hardcoded. Update.

Repo

• eslint.config.js ignore glob - icon demo path hardcoded with element name. Update.
• elements/package.json exports - orphaned entries from renamed elements linger silently. no-missing-package-exports catches missing but not extra. Audit manually.

Docs

• docs/_snippets/ - independent of component docs, easy to miss.
• docs/framework-integration/ - inline code examples with element names.
