[Release] Update the Skill, contracts and breaking-release guidance

[tt-a1i]

Parent

#107

What to build

Publish the invocation-native behavior as a coherent user-facing release. Documentation and the bundled Skill teach the new Agent identity, raw output, partial status, file-backed stages and safe parallel-write guidance.

Acceptance criteria

• The bundled Skill teaches repeatable --agent [alias=]provider:model usage and --providers shorthand.
• The Skill guides callers to partition parallel write ownership and warns about overlapping edits without requiring worktrees.
• CLI references document text, JSON and JSONL output, stdout/stderr separation and exit codes.
• Workflow documentation explains thin review and LLM-driven chain, debate and synthesis.
• Artifact documentation describes Markdown layout, temporary cleanup and persistence.
• Breaking-release notes list removed findings surfaces and migration replacements.
• Examples include multiple models from one Provider and a partial task.
• CLI help, dry-run examples, package smoke tests and installed Skill validation pass.
• The parent spec remains open and unchanged.
