[Bug] Bash permission allowlist not matching piped commands correctly

Bug Description
even though i have setup my settings.json to have

{
"permissions": {
"allow": [
"Bash(grep:*)",
"Bash(find:*)",
"Bash(cat:*)",
"Bash(wc:*)",
"Bash(head:*)",
"Bash(tail:*)",
"Bash(npx vitest:*)",
"Bash(npm run:*)",
"Bash(VITEST_MAX_WORKERS=*)",
"Bash(|grep)",
"Bash(|tail)",
"Bash(|head)",
"Bash(|wc)",
"Bash(| grep)",
"Bash(| tail)",
"Bash(| head)",
"Bash(| wc)"
]
}
}

i am constantly caught approving grep, find head and tail commands. it is maddening.
