Plugin cache_path stored as absolute path breaks in Docker/multi-HOME environments

[joshgoebelwork]

Description

When a plugin is installed, cache_path in config.json is hardcoded to an absolute path
rooted at the install-time $HOME. If ~/.copilot is volume-mounted into Docker (where
$HOME differs), the path doesn't exist and sessionStart hooks silently never fire.

I'm mounting my host ~/.copilot into the active user's home folder in Docker, and that seems
to work for most things, but evidently not plugins. Any help greatly appreciated.

Root Cause

config.json stores:
"cache_path": "/Users/josh/.copilot/installed-plugins/_direct/my-plugin"

Inside Docker ($HOME = /home/deployer), that path doesn't exist.

Expected Behavior

cache_path should be $HOME-relative so it works across environments sharing ~/.copilot.

Workaround

sudo mkdir -p /Users/josh && sudo ln -sfn /home/deployer/.copilot /Users/josh/.copilot
(must be recreated each container start)

Environment

• CLI: 1.0.59
• Host: macOS /Users/josh
• Container: Linux /home/deployer
• ~/.copilot shared via Docker volume mount
