SC-026: install.sh Falls Back When No Platform Detected

Covers: FR-015, Edge case from 2.3 — install.sh target platform not detected: fall back to interactive prompt Type: Edge Case

Given

A generated skill with a valid install.sh
The system has NONE of the standard platform directories (~/.claude/, ~/.github/, .cursor/, etc.)

When

./install.sh is run without --platform or --path flags

Then

The script does NOT silently fail
The script outputs a message listing available platforms and asks the user to specify one
Exit code is 2 (Platform not detected)

Verification Method

Method: CLI command

Steps:

In a clean environment without any platform directories, run: ./install.sh
Check the output for a prompt or platform list
Check exit code: echo $?

Expected evidence: Exit code 2. Output contains a message like "No supported platform detected. Please specify with --platform or --path." Lists available platform options.
