Extends the experimental antigravity host adapter (#147) with full cross-platform Windows support and compatibility with Antigravity 2.0.

Background & Motivation

In #147, the Antigravity CLI host was introduced with a limitation noting "macOS and Linux only: on Windows agy runs hook commands through cmd /c, and this plugin's launcher is a POSIX shell script." On Windows machines, cmd.exe fails to run ./scripts/te-hook, preventing hook execution. Additionally, Antigravity 2.0 native tool signatures (write_file and edit_file with parameter Path) were unmapped.

Key Changes

1. Windows Launchers (plugin/scripts/te-hook.cmd & te.cmd):
   • Implemented native Windows batch launchers matching the te-hook and te shell scripts.
   • Includes dynamic Python 3 discovery: checks TE_PYTHON, searches PATH for python.exe / py.exe (skipping non-functional WindowsApps stubs), and fails open ({}) on errors.
2. Cross-Platform plugin/hooks.json:
   • Updated hook execution to run scripts\te-hook.cmd ... 2>nul || ./scripts/te-hook ..., allowing transparent execution under both Windows (cmd.exe /c) and Unix (sh -c).
3. Antigravity 2.0 Tool Vocabulary:
   • Added native mappings for write_file and edit_file in tokeneconomizer/trace/antigravity.py to correctly track file writes and edits as Write and Edit actions.
4. Host Detection:
   • Improved detect() in tokeneconomizer/plugin/hosts.py to identify both antigravity (Desktop) and antigravity-cli.
5. Testing & Documentation:
   • Extended tests/test_antigravity.py with tests for modern Antigravity tools and launcher script presence.
   • Updated README.md, plugin/README.md, and docs/PLUGIN.md to reflect cross-platform support.

Verification

• python -m pytest tests/test_antigravity.py tests/test_plugin_package.py: 53 passed, 3 skipped.
• Live verified on Windows with both agy CLI and Antigravity 2.0.

Thanks for the contribution. This PR needs a bit of refinements before it can be merged:

1. plugin/hooks.json is what agy runs on macOS and Linux too, through sh -c. There, scripts\te-hook.cmd becomes scriptste-hook.cmd, which is not found, and 2>nul writes a file named nul into the plugin directory on every hook call. One option to try (we haven't tested it on Windows): put the POSIX launcher first (./scripts/te-hook … || scripts\te-hook.cmd …). te-hook fails open with exit 0, so sh never reaches the Windows half.
2. In both .cmd files, every exit /b %ERRORLEVEL% sits inside a ( … ) block. cmd expands it when it reads the block, before Python runs, so the launcher always exits 0. Please use setlocal EnableDelayedExpansion with !ERRORLEVEL!, or move the call out of the block.
3. Please have the Windows launcher pick the first Python >= 3.10, as #194 does for POSIX.
4. Please keep the docs to what was tested: the agy version and Windows version you ran, and no "dual .cmd/.sh launchers" (there is no .sh launcher). The docs also still send Windows users to ~/.tokeneconomizer/bin/te, which is a /bin/sh script.
5. Please move the Antigravity 2.0 parts (write_file/edit_file, the product detection) to a separate PR, with a redacted real transcript showing those tool names. Nothing in the repo shows them yet, and the product branch never runs because hooks.json always passes --host antigravity.
6. Please mark the .cmd files eol=crlf in .gitattributes.
