[BUG] Fix indentation of MULTI-STEP FIX substeps in align output

[ddjain]

Bug Description

Substeps under "MULTI-STEP FIX (N steps):" are not indented; only the first line is. Indent all lines of the fix preview so substeps align under the parent fix (e.g. in align CLI, prefix each line of fix.preview() with the same leading spaces).

To Reproduce

• Use a repository that does not have CLAUDE.md or AGENTS.md (so the claude_md_file fix is offered).
• Set your API key:
  export ANTHROPIC_API_KEY=<your-key>
• Run:
  uv run agentready align <path_to_target_repo>

Actual Behavior

Multi-step fix substeps are indented under the fix so the hierarchy is clear. For example:

  1. [claude_md_file] Run Claude CLI to create CLAUDE.md, then move content to AGENTS.md
     MULTI-STEP FIX (2 steps):
       1. RUN claude -p 'Initialize this project with a CLAUDE.md file' --allowedTools Read,Edit,Write,Bash
       2. Move CLAUDE.md content to AGENTS.md and replace CLAUDE.md with @AGENTS.md
