Add multi-output and no-quote options to collect workflow

[yuki-yano]

Summary

• Add --output (multi) and --no-quote flags to collect to allow buffering and stdout teeing simultaneously.
• Improve quote processing to trim wrapped-line whitespace while preserving Markdown list protection.
• Update docs with tmux clipboard example and output option explanations.

Details

• collect: supports multiple --output buffer/stdout and skips quote decoration when --no-quote is set.
• quoteProcessor: cleans up indented continuations and trailing spaces to stabilize one-line output when needed.
• Docs/Tests: refreshed modes.md; added coverage for new formatting cases.

Testing

• bun test test/utils/quoteProcessor.test.ts
