Add `--include-logs` option to include `git log --name-status` output

[yamadashy]

Repomix already supports pulling in diffs via --include-diffs (see PR #533). This enhancement will let users bundle recent commit history—specifically the output of git log --name-status—into their archive with a simple flag.

---

Motivation:

• Change Visibility: Shows which files changed in each commit, helping reviewers and LLMs trace code evolution.
• Context: Complements low-level diffs with a concise, high-level history.
• Configurability: Users can limit how many commits to include.

---

Proposed Changes:

1. CLI Definition

   // in src/cli/cliRun.ts (and types.ts)
   .option('--include-logs', 'include git log --name-status output in the archive')
   .option(
     '--include-logs-max-commits <number>',
     'maximum number of commits to include in git log (default: 100)',
     { default: 100 }
   )

2. Config Schema

   interface RepomixConfigCli {
     // ...existing fields
     output?: {
       git?: {
         includeLogs?: boolean;
         includeLogsMaxCommits?: number;
       }
     }
   }

3. Git Collection Logic

   • In your git collector (e.g. src/core/git/gitCollector.ts), when config.output.git.includeLogs is true, run:

     git log --name-status -n ${config.output.git.includeLogsMaxCommits}

   • Emit the result as a file (e.g. repomix-git-log.txt) inside the output bundle.

4. Documentation & Tests

   • Update command-line-options.md and README.md to document --include-logs and --include-logs-max-commits.

   • Add tests under tests/ to verify:

     • repomix --include-logs produces repomix-git-log.txt.
     • The --include-logs-max-commits override is respected.
     • Default behavior uses 100 commits.
