Add logcli tool for querying Grafana Loki logs

[ooloth]

💪 What

• Add logcli tool module with install, update, and uninstall scripts
• Update CLAUDE.md to reference eza and logcli as examples of simple Homebrew formula tools

🤔 Why

• Enable querying Grafana Loki log aggregation systems using LogQL from the command line
• Provide a clean example (alongside eza) of how to add a simple Homebrew-based tool to this dotfiles repository

👀 Usage

Once installed, use logcli to query Grafana Loki servers:

# Query logs with LogQL
logcli query '{app="myapp"}'

# Stream live logs
logcli tail '{job="myjob"}'

# Get labels
logcli labels

👩‍🔬 How to validate

1. Ensure the DOTFILES environment variable is set (e.g., export DOTFILES=/path/to/dotfiles)
2. Install logcli:

   ${DOTFILES}/tools/logcli/install.bash

3. Verify installation:

   logcli --version

4. Update logcli:

   ${DOTFILES}/tools/logcli/update.bash

5. Uninstall logcli:

   ${DOTFILES}/tools/logcli/uninstall.bash

6. Verify the scripts follow the same pattern as tools/eza/ (another simple Homebrew formula)
