chore: add changeset for 1.0.0 release

[TabishB]

OpenSpec 1.0 — The OPSX Release

The workflow has been rebuilt from the ground up.

Breaking Changes

• Old /openspec:* commands removed
• Config files (CLAUDE.md, .cursorrules, AGENTS.md, project.md) no longer generated
• Run openspec init to upgrade

What Changed

Before	After
Static prompts (same every time)	Dynamic instructions (context + rules + template based on artifact state)
Phase-locked (proposal → apply → archive)	Action-based (any action anytime, artifact graph tracks state)
Text-based spec merging	Semantic syncing (ADDED/MODIFIED/REMOVED/RENAMED at requirement level)
8+ scattered config files	Single .claude/skills/ directory (Agent Skills standard)
3 commands	10 commands including explore, verify, bulk-archive, onboard

New Commands

• /opsx:explore — Think through ideas before committing
• /opsx:new — Start a change
• /opsx:continue — Create one artifact at a time (step-through)
• /opsx:ff — Create all artifacts at once (fast-forward)
• /opsx:apply — Implement tasks
• /opsx:verify — Validate implementation matches artifacts
• /opsx:sync — Sync delta specs to main specs
• /opsx:archive — Archive completed change
• /opsx:bulk-archive — Archive multiple changes with conflict detection
• /opsx:onboard — Guided 15-minute walkthrough

New Features

• Onboarding skill — 11-phase guided first experience with codebase-aware task suggestions
• 21 AI tools — Claude, Cursor, Windsurf, Continue, Gemini, GitHub Copilot, Amazon Q, and 14 more
• Interactive setup — Animated welcome screen + searchable multi-select
• Customizable schemas — Define workflows in openspec/schemas/ without touching code

Bug Fixes

• Claude Code YAML parsing failure with colons in names
• Task file trailing whitespace handling
• JSON instruction output separating context/rules from template

Documentation

• New getting-started, CLI reference, concepts docs
• Removed misleading mid-flight editing claims
• Added migration guide

Title check	⚠️ Warning	The PR title states 'chore: add changeset for 1.0.0 release' but describes a v0.24.0 feature changeset with breaking changes including OPSX rebrand, workflow rewrite, command removals, and semantic spec syncing—not a routine 1.0.0 release chore.	Update the title to accurately reflect the substantial nature of changes, such as 'feat!: add changeset for OPSX 1.0.0 rebrand and workflow rewrite' to convey the breaking changes and major feature overhaul.
