Docs and installer polish (v1.1.3)

• README: clarified installation modes (standard, editable, and NLP extras), tightened wording, and refreshed badges/links.
• Setup: improved guidance printed by setup.sh after environment creation; clarified quick start steps.
• Requirements: synced with current packaging to ensure local venv installs match pyproject.toml expectations.
• Normalization: fold fullwidth square brackets 【】 to ASCII [] by default; add --keep-fullwidth-brackets to preserve them; dagger † remains untouched.
• Minor behavior change: default folding of fullwidth brackets; use the new flag to opt out.
