refactor: extract SessionStart hook into language-agnostic install-deps.sh

Replaces the inline uv-specific hook command with a shell script that
detects the package manager from lock files (uv, npm, yarn, pnpm) and
installs deps into CLAUDE_PLUGIN_DATA. Hook reduces to a single sh call.

Bump 1.3.1 → 1.3.2
