Document recommendation to export SENTRY_SPOTLIGHT=1 in shell profiles

[dcramer]

Description

We should recommend users to export SENTRY_SPOTLIGHT=1 in their shell profiles for better server configuration.

Proposed Solution

Add documentation that recommends users add the following to their shell profile (.bashrc, .zshrc, etc.):

export SENTRY_SPOTLIGHT=1

This would provide a more persistent configuration approach compared to setting it per-session.

Benefits

• Users won't need to remember to set the environment variable each time
• Provides a cleaner developer experience
• Reduces configuration friction

Tasks

• [ ] Update documentation to include shell profile configuration recommendation
• [ ] Consider adding this to the setup/installation guide
• [ ] Add examples for different shells (bash, zsh, fish, etc.)
