Antigravity hook can break after install because statusLine stores stale absolute CLI path

[ozymandiashh]

Problem

codeburn antigravity-hook can leave Antigravity configured with an absolute statusLine.command path that later becomes stale. When that target no longer exists, Antigravity repeatedly fails the statusLine command, then auto-disables it after consecutive failures. From that point, CodeBurn reports Antigravity usage as €0 / 0 calls even though agy was used.

This is related to, but distinct from #381. That issue covers missed usage after the CLI exits. This issue is about the live capture hook itself becoming broken because the configured command points at a removed/moved CodeBurn build artifact.

Evidence

Local Antigravity settings contained a command like:

{
  "statusLine": {
    "type": "command",
    "command": "'/path/to/node' '~/codeburn-agy-statusline/dist/cli.js' agy-statusline-hook"
  }
}

Recent Antigravity CLI logs then showed:

statusline: command failed: exit status 1
Error: Cannot find module '~/codeburn-agy-statusline/dist/cli.js'
...
statusline: auto-disabled after 30 consecutive failures

After that, CodeBurn showed Antigravity for the day as:

cost: 0
calls: 0
sessions: 0

while Claude and Codex continued to report normally.

Expected

The Antigravity hook should not depend on a fragile absolute path to a temporary/local CodeBurn checkout or build output.

Possible fixes:

• install the hook using the persistent codeburn binary path, similar to the menubar persistent path handling;
• make codeburn antigravity-hook install detect and repair stale CodeBurn-owned statusLine commands;
• warn clearly when the installed Antigravity statusLine command points to a missing target;
• avoid Antigravity silently staying in a broken capture state until the user manually runs codeburn antigravity-hook install --force.

Workaround

Running this repairs future capture:

codeburn antigravity-hook install --force

but historical usage during the broken/auto-disabled window remains missing.

Environment

• CodeBurn: 0.9.11
• Platform: macOS
