[main] Update checkout and align agentic workflows

[Evangelink]

Supersedes #10164.

• Update all actions/checkout references to v7.0.1 and pin generated workflows to 3d3c42e5aac5ba805825da76410c181273ba90b1.
• Update explicit agentic workflow sources and .github/aw/actions-lock.json, then regenerate all 30 workflows in strict mode with gh-aw v0.83.1.
• Pin github/gh-aw-actions setup actions to the v0.83.1 commit and align the remaining agentic action/container dependencies.
• Apply the current gh-aw dispatcher skill layout.
• Remove the obsolete FV documentation validation workflow and its workflow catalog entry.

Validation:

• gh aw compile --strict --validate --no-emit --no-check-update
• actionlint: 30 workflows checked, no issues
• verified all generated lock metadata is strict and compiled with v0.83.1

.github/agents/agentic-workflows.md:2

• Renaming this file leaves .github/workflows/README.md:37 linking to the removed ../agents/agentic-workflows.agent.md, so the documented dispatcher link now returns 404. Update that catalog link to the new filename (or retain the old filename).
