builder: Remove unused INSTALL_DEPENDENCIES variable #11

Description

The builder feature's install script contains an unused INSTALL_DEPENDENCIES variable that appears to be a copy-paste artifact from the bosh-cli script.

Current State

File: src/builder/install.sh

• Line 4: : ${INSTALL_DEPENDENCIES:=true} - defined but never used

Analysis

The builder tool is a simple static site generation binary that only requires:

• curl and ca-certificates for downloading
• Basic file operations for installation

Unlike bosh-cli which installs additional development dependencies (build-essential, ruby, etc.), the builder feature doesn't need any optional dependencies, making the INSTALL_DEPENDENCIES variable unnecessary.

Proposed Solution

Remove the unused variable from line 4:

# Remove this line:
: ${INSTALL_DEPENDENCIES:=true}

Files Affected

• src/builder/install.sh (line 4)

Context

This appears to be a copy-paste oversight where the variable was copied from bosh-cli/install.sh but the corresponding functionality was never implemented (and isn't needed for this feature).
