Reorganize badges on README

[minggangw]

Changes

README.md

Badges (lines 3–8):

• Reorganized from 9 badges on a single line to 6 focused badges, each on its own line: npm version, npm downloads, GitHub stars, coverage, Node version, TypeScript
• Removed lower-value badges: license (visible in repo sidebar), code style (developer-facing), last commit (redundant with CI table)

CI status table (lines 10–12):

• Renamed headers: ROS Distro* → ROS 2 Distro, Status → CI Status
• Replaced plain text distro list with a ROS 2 badge showing all supported distros
• Stacked CI badges vertically with <br> for proportional scaling
• Simplified table separator to minimal | :---: | :---: |
• Removed orphaned footnote note

Intro (line 14):

• Added one-line feature highlights

Performance table (line 246):

• Right-aligned numeric columns for readability

.prettierignore (new)

• Exclude README.md and scripts/npmjs-readme.md from Prettier auto-formatting to prevent table separator padding from being re-expanded on commit

Fix: #1482

Pull request overview

This PR updates the project’s README presentation by reorganizing the top-level badges/CI status section and lightly reformatting the benchmarks section to improve readability.

Changes:

• Split the single-line badge block into multiple lines and add a GitHub stars badge.
• Replace the ROS distro/CI status table with a ROS 2 “supported distros” badge plus per-platform workflow badges.
• Reformat the Performance Benchmarks table for numeric alignment and move the methodology note after the table.

The PR title says this is a reorganization of badges, but this change also drops the GitHub license badge and the Prettier/code-style badge (previously present in the single-line badge row). If the intent is only to reorder, consider re-adding those badges or clarify that removing them is desired.

[Copilot]

The Markdown table header/separator uses extremely long runs of spaces and dashes, which makes the README harder to edit and increases diff noise without affecting rendering. Consider simplifying the table header and alignment row to a minimal form (e.g., standard | --- | --- |) while keeping the same displayed content.
