Detect the Antigravity CLI by image name when CommandLine is empty

[btsouth]

Hardens Antigravity process detection for the standalone CLI (#412).

The detector's PowerShell filter already selects agy.exe by image name, but the parser then re-derived the match from the command line. If WMI returns an empty CommandLine for a running agy.exe, the emitted line was just the PID, nothing matched, and Ceiling reported "Antigravity language server not running" even though the CLI was up and its local quota API answered.

The query now emits <pid>\t<image name>\t<command line>, and a matched agy.exe / antigravity-cli image name is accepted even when the command line is empty. Two-column output still parses, so the existing paths are unchanged.

I could not reproduce the reporter's exact failure on a Windows 11 VM: with a stand-in agy.exe, detection matched and advanced to port discovery, and even an elevated agy.exe exposed its CommandLine to a non-elevated query. This change covers the empty-CommandLine case, which is the most likely cause, without regressing the matched paths.

Testing: cargo test (rust lib, 1237 tests), cargo clippy --all-targets -D warnings, cargo fmt --check. Added tests for the three-column line, the empty command line, and a non-Antigravity image name.

Note

Detect Antigravity CLI by image name when CommandLine is empty

Updates AntigravityProvider process detection to capture the image name alongside PID and command line from PowerShell/WMI output. Adds is_cli_image_name to classify processes like agy.exe or names containing antigravity-cli even when the command line is empty. The parse_process_info parser now handles the new three-column format while remaining compatible with the legacy two-column format.

• CLI classification combines command-line and image-name detection; IDE classification and connection-argument extraction still rely on the command-line field
• Adds regression and negative tests covering three-column parsing, empty command-line detection, and rejection of unrelated image names like chrome.exe
