Support for pi-coding-agent session logs

[arunsathiya]

ccusage doesn't work with pi-coding-agent (https://github.com/badlogic/pi-mono/tree/main/packages/coding-agent), an alternative Claude CLI. The pi agent stores its session data in ~/.pi/ rather than ~/.claude/projects/, so ccusage can't find or parse the logs.

Would it be possible to add support for pi-coding-agent's log format/location? I've opened a corresponding issue on their repo to discuss whether they could adopt a compatible log format: badlogic/pi-mono#104

While I appreciate the initiative, I do not think pi is big enough to be considered for inclusion in ccusage. If the ccusage maintainers do want to add support, I've created a detailed outline of what's needed. It should be very easy compared to Claude Code and Codex, as the pi's session files already contain all the information (per assistant message (== LLM request) token counts, cost, model information).

Thanks @badlogic. Happy to help test if support is added.
