perf(deploy): leverage pre-installed jq on ubuntu-24.04 runners

Removes conditional jq installation logic since jq 1.7.1 is pre-installed
on ubuntu-24.04 GitHub Actions runners.

Changes:
- Remove apt-get install check/fallback for jq
- Simplify tool verification to direct version checks
- Remove timeout command check (coreutils guaranteed on Ubuntu)
- Maintain Bash 4.0+ version check as safeguard

Benefits:
- Faster workflow execution (no apt-get operations)
- Simpler verification step (12 lines reduced to 8)
- Relies on documented runner capabilities

- jq 1.7.1-3ubuntu0.24.04.1 confirmed pre-installed
