fix: pin prompt URLs to version tag instead of main branch (#191)

The init command generates agent files that reference prompts via
raw.githubusercontent.com URLs pointing at the main branch. If files
are moved or renamed, all previously deployed agent files break.

Replace "main" with "v{{ compiler_version }}" in all prompt and
AGENTS.md URLs within the init-agent template and the console output
hint. This leverages the existing version substitution mechanism and
is consistent with how binary download URLs are already pinned.
