chore(pr): add PR readiness workflow

[BunsDev]

Summary

• Add a repository PR template with explicit context, validation, and readiness sections.
• Add AGENTS.md guidance for PR-ready branch preparation and parallel-agent PR handoffs.
• Add a bundled pr-ready skill and tighten the batch skill so worker branches produce review-ready PRs.

Context

• Related issue/user request: consolidate remaining branch/worktree work back toward main.
• Scope: PR readiness workflow docs/template plus bundled skill guidance.
• Non-goals: no TUI behavior changes; the older accessibility/auth UI branch content already landed separately or was intentionally left out.

Changes

• Added .github/PULL_REQUEST_TEMPLATE.md.
• Documented PR readiness expectations in AGENTS.md.
• Added pr-ready bundled skill aliases and tests.
• Updated the batch bundled skill prompt to require PR template awareness, body-file usage, verification evidence, and parseable PR output.

Validation

Record exact commands and outcomes. Mark items N/A with a reason when they do not apply.

• git diff --check - PASS
• cargo fmt --all - PASS
• cargo check --workspace - PASS
• cargo clippy --workspace --all-targets -- -D warnings - PASS
• cargo test --workspace - PASS
• Targeted/manual checks:
  • cargo test --package claurst-tools pr_ready_skill_enforces_template_and_body_file_contract - PASS
  • cargo test --package claurst-tools batch_skill_requires_pr_readiness_contract_for_workers - PASS
• Not run: N/A

PR Readiness

• Diff is limited to the intended files.
• Generated files were not edited by hand.

• No secrets, credentials, local paths, or unrelated logs are included.
• Remaining risks or follow-up work are listed above.
