fix: correct awk quoting in aiden-runner workflow version extraction

[Copilot]

Problem

The aiden-runner CI pipeline was failing with:

awk: cmd. line:1: $1 == \"version\" { print $2; exit }
awk: cmd. line:1:       ^ backslash not last character on line
Error: Failed to extract version from aiden-runner.rb

Root Cause

The awk command used \" inside a single-quoted bash string:

VERSION="$(awk '$1 == \"version\" { print $2; exit }' aiden-runner.rb | tr -d '\"')"

In bash, single quotes suppress all escape processing — the \" is passed literally to awk as a backslash followed by a double-quote, which awk cannot parse.

Fix

Remove the backslashes so the double-quotes are passed correctly to awk (single quotes in bash make interior double-quotes entirely safe):

VERSION="$(awk '$1 == "version" { print $2; exit }' aiden-runner.rb | tr -d '"')"

Verified locally: the corrected command correctly extracts 0.1.24 from aiden-runner.rb.
