docs: sync AGENTS.md with AGENT_CONFIG for missing agents

[Quratulain-bilal]

Summary

• Added missing agents (Antigravity, Mistral Vibe) to the supported agents table
• Fixed Cursor categorization: moved from CLI-Based to IDE-Based (matches requires_cli: False in
  AGENT_CONFIG)
• Added missing agents to CLI-Based list (Codex, Auggie, iFlow)
• Added missing agents to IDE-Based list (Kilo Code, Roo Code, Trae, Antigravity)
• Updated Markdown Format users list and Directory Conventions sections

Test plan

• Verified all changes match AGENT_CONFIG in src/specify_cli/__init__.py
• No code changes, documentation only

Pull request overview

This PR updates AGENTS.md to better reflect the agent metadata defined in AGENT_CONFIG (in src/specify_cli/__init__.py), primarily by adding missing agents and aligning category/format guidance.

Changes:

• Added Antigravity and Mistral Vibe to the supported agents table.
• Updated CLI-based vs IDE-based agent categorization (notably moving Cursor to IDE-based) and expanded both lists.
• Refreshed the Markdown “Used by” list and the Directory Conventions section with additional agent-specific paths.

Comments suppressed due to low confidence (1)

AGENTS.md:406

• This Directory Conventions list includes “Antigravity: .agent/commands/”, but Antigravity is treated as a skills-migrated agent in the CLI (explicit .agent/commands usage is deprecated and --ai-skills is required when --ai agy is provided). Update this entry to reflect the recommended skills path (e.g., .agent/skills/) and/or call out the deprecation so users don’t scaffold an unsupported layout.

  - Cursor: `.cursor/commands/`
  - Windsurf: `.windsurf/workflows/`
  - Kilo Code: `.kilocode/workflows/`
  - Antigravity: `.agent/commands/`

AGENTS.md:54

• Antigravity is added as a supported agent, but the table doesn’t indicate the --ai key used by the CLI. In AGENT_CONFIG the key is agy, and users must use --ai agy (often with --ai-skills). Consider including agy in the table (either in the CLI Tool column or via a dedicated “--ai key” field) so the doc stays actionable.

The supported agents table now lists Cursor as having no CLI tool, but the --ai key in AGENT_CONFIG is still cursor-agent. Since this doc is used as a reference for adding/updating agents, consider including the --ai key (e.g., cursor-agent) in this row (or adding a separate “--ai key” column) to avoid readers assuming the key is cursor.

This issue also appears on line 52 of the same file.

AGENTS.md:409

• This lists Antigravity as .agent/skills/, but the build/config currently generates Antigravity command files under .agent/commands/ and uses --ai agy as the identifier. Consider updating this bullet (or documenting both the commands dir and the skills dir) so it stays consistent with runtime/release packaging.

- **IDE agents**: Follow IDE-specific patterns:
  - Copilot: `.github/agents/`
  - Cursor: `.cursor/commands/`
  - Windsurf: `.windsurf/workflows/`
  - Kilo Code: `.kilocode/workflows/`
  - Antigravity: `.agent/skills/` (skills-based)
