/**
|
|
* Statusline Counts — lightweight project-scoped observation counter
|
|
*
|
|
* Returns JSON with observation and prompt counts for the given project,
|
|
* suitable for integration into Claude Code's statusLineCommand.
|
|
*
|
|
* Usage:
|
|
* bun statusline-counts.js <cwd>
|
|
* bun statusline-counts.js /home/user/my-project
|
|
*
|
|
* Output (JSON, stdout):
|
|
* {"observations": 42, "prompts": 15, "project": "my-project"}
|
|
*
|
|
* The project name is derived from basename(cwd). Observations are counted
|
|
* with a WHERE project = ? filter so only the current project's data is
|
|
* returned — preventing inflated counts from cross-project observations.
|
|
*
|
|
* Performance: ~10ms typical (direct SQLite read, no HTTP, no worker dependency)
