chore: promote Farm v2 stable release

[Copilot]

• Inspect branch, working tree, and shallow clone state
• Unshallow repository and fetch origin/main explicitly
• Merge origin/main into current branch
• Resolve Cargo.lock merge conflict by keeping stable Farm 2.0.0 internal crate versions and origin/main Sass grass dependency
• Run minimal validation: conflict marker search, git diff --check, cargo metadata --no-deps
• Create true two-parent merge commit and push result
