Refresh editor and AI adapter guidance

[helizaga]

Summary

• update Antigravity integration to use agy-ide for the editor and add agy as a terminal-agent adapter
• prefer Cursor's current agent CLI while retaining legacy command fallbacks
• refresh AI/editor installation guidance, mark Atom and Continue as legacy compatibility, and emphasize the safe generic PATH fallback
• improve README positioning, surface agent automation earlier, document complete config precedence, and regenerate all shell completions

Why

The adapter matrix and documentation had drifted from current product commands and installation packages. In particular, Cursor now installs agent, Antigravity distinguishes agy-ide from agy, and the documented GitHub Copilot package was obsolete.

Validation

• git diff --check
• shellcheck bin/gtr bin/git-gtr lib/*.sh lib/commands/*.sh adapters/editor/*.sh adapters/ai/*.sh
• ./scripts/generate-completions.sh --check
• focused BATS: 54/54 passed across adapters, help, completions, and launch configuration
• full BATS: 553/555 passed locally; the two failures reproduce unchanged on origin/main:
  • cmd_clean --merged uses nested registered worktree path
  • cmd_config set --global writes to global config (sandbox cannot write the configured global Git path)

Summary by CodeRabbit

• New Features

  • Added Antigravity support for editor and AI workflows.
  • Added generic PATH fallback support for compatible command-line tools.
  • Updated Cursor integration to support the current agent command.
  • Added Antigravity to shell completion suggestions.

• Documentation

  • Expanded guidance for AI agents, adapters, automation, configuration precedence, and supported tools.
  • Clarified legacy integrations and native Windows support.

• Tests

  • Added coverage for Antigravity and updated Cursor adapter behavior.

Walkthrough

Changes

The change adds Antigravity adapter support, updates Cursor CLI detection and launch order, marks Atom and Continue as legacy entries, refreshes shell completions, and updates usage and configuration documentation.

AI adapter support

Layer / File(s)	Summary
Adapter registry and launch behavior lib/adapters.sh, adapters/ai/cursor.sh, tests/adapters.bats	The registry adds Antigravity and uses agy-ide for the editor. Cursor detection and launch now prefer agent, with legacy fallbacks. Tests cover commands, flags, and working-directory handling.
CLI listings and completion support lib/commands/adapter.sh, lib/commands/help.sh, completions/*, tests/adapters.bats	Help output and completions include Antigravity. Atom and Continue appear as legacy compatibility entries. Tests cover ready and missing legacy adapter statuses.
Usage and configuration documentation README.md, docs/configuration.md, docs/troubleshooting.md, CHANGELOG.md	Documentation covers updated commands, PATH fallbacks, configuration precedence, adapter coverage, and Windows shell requirements.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: 🔵 Low · up to 28707

The PR updates adapter command selection and adds new integrations. It is mergeable with owner awareness that Cursor’s generic agent command could resolve to an unintended PATH executable and run with the selected worktree and user environment.

Poem

I’m a rabbit with adapters bright,
Antigravity joins the flight.
Cursor finds agent today,
Legacy tools remain in play.
Docs and completions guide the way.

standard agy executable instead of agy-ide, and apply the same command-name
change in tests/adapters.bats and docs/configuration.md. Preserve the existing
adapter identifier, install guidance, and configuration behavior.

In `@lib/commands/adapter.sh`:
- Around line 60-61: Update _print_adapter_list and its adapter tables to
visibly mark atom and continue as legacy entries, or move them into a separate
legacy compatibility section; ensure they are no longer presented as ordinary
registry rows while preserving the existing listing output for current adapters.
