fix: typo in color variable name + cross-platform IP detection fallback

[kbrenner-dev]

Fixes

1. Typo in cinelog.plugin.zsh

BAISC_MAGENTA → BASIC_MAGENTA

This typo means the variable is defined as BAISC_MAGENTA but any code referencing BASIC_MAGENTA would get an empty string instead of the magenta color escape code.

2. Cross-platform IP detection in http_server.py

The current implementation uses ip route get 1 | awk '{print $7}' which only works on Linux and fails silently on macOS/BSD. Added a socket-based fallback which works on all platforms.

3. Missing Python dependencies for hist

The hist script requires both docopt and prompt_toolkit, but the README only mentioned apt install python3-docopt — prompt_toolkit was completely missing from the installation instructions, causing the script to fail on a fresh install.

Added requirements.txt with both dependencies and updated the README accordingly.

4. Hardcoded ~/.zim/modules/cinelog/ path

Both cinelog.plugin.zsh and http_server.py had the zim install path hardcoded, which breaks the plugin for anyone using oh-my-zsh, antigen, zplug, or a manual install.

Fix:

• In cinelog.plugin.zsh: added CINELOG_DIR="${0:A:h}" — ZSH's built-in way to get the current script's directory at runtime, works with any plugin manager.
• In http_server.py: replaced hardcoded path with os.path.dirname(os.path.realpath(__file__)) as fallback, also respects a CINELOG_DIR env var exported by the plugin.
