feat: add codex template

[kemingy]

• add codex.envd template, try it with envd new -t codex
• change codex from gnu to musl to avoid the glibc version requirements
• only install the uv python once when dev=True
• use apt glob syntax to avoid "Unable to locate package libtinfo5" on Ubuntu 24:04

[Copilot]

Pull Request Overview

This PR updates the codex agent installation to use musl-based binaries instead of glibc-based ones, updates base APT packages to support both version 5 and 6 of libtinfo and libncursesw libraries, and adds a new codex template file. Additionally, it optimizes UV Python installation to skip for sudo when dev=True.

• Changed codex agent downloads from linux-gnu to linux-musl builds
• Updated base APT packages to use pattern matching for library versions (libtinfo[56] and libncursesw[56])
• Added early return in UV compilation when dev=True to avoid redundant Python installation
