feat(skills): Add backport-pr skill - #22434

Conversation
Adds a skill that backports a merged PR to a maintenance major branch (v10 by default, with a target-major parameter for older majors like v9). It cherry-picks the PR's squash-merge commit, namespaces the commit/PR title scope (e.g. fix(core) -> fix(v10/core)), and opens a draft backport PR following the convention used for the v9 backports.

Run verification before finalizing the commit so yarn format changes are folded into the pushed commit instead of left uncommitted. Replace the personal ab/ branch prefix with a neutral backport/ default.
The branch name isn't load-bearing; only the base branch and commit/PR title conventions matter.
The amend replaces the body with the one-line Backport of: note, so drop the contradictory keep-the-body wording. Use a prebuilt namespaced title placeholder so a scope-less source PR yields fix(v10): not fix(v10/):.
gh pr view takes either, so pass the input through unchanged and use the resolved number for the Backport of: reference so URLs render correctly.
Use lint:fix so auto-fixable issues are applied, git add -u so a repo-wide format doesn't stage unrelated edits, and capture the gh pr create URL for the cross-link comment.
The commands now match the prose: amend with the namespaced title for a single squash commit, or fold fixes with --no-edit for multi-commit backports where the title lives on the PR.

What
Adds a
backport-prskill that backports a merged PR to a maintenance major branch.v10, with a target-major parameter for older majors (e.g.v9).fix(core):becomesfix(v10/core):.Backport of: #<pr>body and cross-links the original.Why
developis now v11 and released changes go onto the previous major's maintenance branch. This codifies the manual convention we used for the v9 backports so it's repeatable and consistent.
