v1.0.0

Added

• 1.0 GA migration guide — docs/migration/v1.0.md.
• Mermaid guide — docs/mermaid-demo.md with PR bot samples #5 / #7.
• validate --mermaid error styling — red error nodes and amber blocked-upstream nodes on failed validation.

Changed

• Pipeline schema v2 only — v1 documents rejected at load/validate.
• Legacy pattern validation — monorepo action paths, @master pins, and manual export uploads are errors (not warnings).
• init / compile defaults — v2 pipeline YAML; compile-check pin @v1.0.0.
• Examples and docs — all examples migrated to v2; action pins @v1.0.0; README trimmed for GA.
• CI — strict validate for meta pipeline, run-tag-release, and compile-check examples.

Removed

• Pipeline schema v1 support (file format with top-level stages:).
• Deprecation warning mode for patterns removed in this release (see v0.5 migration).

Fixed

• findOrphanWorkflows — resolve --repo-root to an absolute path so orphan detection matches stage/companion references.
