Hardcoded ~/.cache/ path instead of using $XDG_CACHE_HOME

[powerman]

Updating from previous commit to latest 3123983 result in breaking plugin:

[ERROR][2025-10-18 13:39:05] ...p/_transport.lua:36 "rpc" "/home/powerman/.local/share/nvim-ai-dev/lazy/copilot.lua/copilot/linux-x64/copilot-language-server-1.384.0" "stderr" "Error: EACCES: permission denied, mkdir '/home/powerman/.cache/pkg'\n at Object.mkdirSync (node:fs:1363:26)\n at Object.mkdirSync (pkg/prelude/bootstrap.js:1639:33)\n at createDirRecursively (pkg/prelude/bootstrap.js:256:8)\n at createDirRecursively (pkg/prelude/bootstrap.js:255:5)\n at process.dlopen (pkg/prelude/bootstrap.js:2222:7)\n at Object..node (node:internal/modules/cjs/loader:1869:18)\n at Module.load (node:internal/modules/cjs/loader:1445:32)\n at Function._load (node:internal/modules/cjs/loader:1267:12)\n at TracingChannel.traceSync (node:diagnostics_channel:322:14)\n at wrapModuleLoad (node:internal/modules/cjs/loader:237:24)\n"

This happens because I'm running AI in a firejail sandbox, which restrict access to $HOME and provide own cache dir for AI sandbox:

$ ls ~/.cache
ls: cannot open directory '/home/powerman/.cache': Permission denied
$ echo $XDG_CACHE_HOME
/home/powerman/.cache-ai-dev

Hardcoding paths like ~/.cache is a bad practice, please use $XDG_CACHE_HOME instead (if it is set).

P.S. I'm not sure is this a right repo for the report - at a glance it looks like main.js (which contains a hardcoded path) may import this part of code from some other dependency.

Yeah from what I can see this is an issue on the LSP-side :(
I recommend you open an issue here.
