Subject: [PATCH 1/2] feat(testing): add ShellSpec tests for all shell scripts
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Created comprehensive test coverage for 10 shell scripts plus a coverage validation test. Each script now has a dedicated spec file that tests its functionality through static analysis and behavioral assertions using the ShellSpec framework.

New spec files:
- install_spec.sh: tests Nix installation, OS detection, USER handling, git ops
- update_gitalias_spec.sh: tests gitalias download and error handling
- kyber_setup_spec.sh: tests Tailscale installation and systemd integration
- kyber_rekey_spec.sh: tests SSH rekey logic and failure handling
- cliproxyapi_spec.sh: tests config generation and binary detection
- keepalive_spec.sh: tests curl behavior and error tolerance
- code_syncer_spec.sh: tests VS Code extension syncing and filtering
- brew_upgrader_spec.sh: tests brew upgrade execution
- dotfiles_updater_spec.sh: tests branch detection and git operations
- neovim_tests_spec.sh: tests plenary.nvim handling and test execution
- coverage_spec.sh: enforces that all scripts have corresponding tests

From bdcc25573a0b10b42383f9dcb87255777bdf5ba9 Mon Sep 17 00:00:00 2001
From: Shun Kakinoki <shunkakinoki@gmail.com>

Subject: [PATCH 2/2] fix(testing): fix shellcheck and shellspec warnings in
 tests
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Add SC2034 (unused variable) and SC2016 (single quotes) suppressions
- Fix grep patterns using -- to properly handle option-like strings
- Redirect stderr to stdout to capture all output in shellspec tests
