Remove trailing slashes and update redirected Ultralytics URLs

[pderrenger]

Normalizes Ultralytics link formatting and refreshes links whose destinations have permanently moved. Text-only change: no hook logic, packaging, or workflow behavior is touched.

Trailing slashes (7 URLs, 3 files)

Removed the terminating path slash from every ultralytics.com / *.ultralytics.com URL. Applied with a regex fixer validated against positive and negative cases first (subdomains, protocol-relative, bare host, fragment/query, sentence-final punctuation, markdown/HTML/backtick delimiters vs. path separators, emails, templates, ellipsis placeholders).

• README.md — www.ultralytics.com/ (x2), community.ultralytics.com/, docs.ultralytics.com/help/contributing/ (x2)
• .github/ISSUE_TEMPLATE/config.yml — community.ultralytics.com/
• .github/ISSUE_TEMPLATE/bug-report.yml — docs.ultralytics.com/help/minimum-reproducible-example/

All seven destinations verified 200 in their slashless form.

Redirect refresh (3 accepted)

• opensource.org/license/agpl-v3 -> opensource.org/license/agpl-3.0 — OSI 301, and already the form used in the main ultralytics README.
• reddit.com/r/ultralytics -> www.reddit.com/r/ultralytics/ — 301 to the canonical www host, matching the social badge block in the main ultralytics README. Applied to both the README badge and the ⌨️ Reddit contact link in .github/ISSUE_TEMPLATE/config.yml.

Deliberately left alone

• ultralytics.com/discord and ultralytics.com/bilibili — vanity shortlinks meant to stay redirects.
• server=https%3A%2F%2Fcommunity.ultralytics.com in the Forums badge — URL-encoded parameter, kept byte-identical.
• pre-commit.com/, python.org/ — non-Ultralytics domains, out of scope for the slash rule.
• ultralytics.com/license header lines — written by Ultralytics Actions, already slashless.

No dead links or homepage collapses were reported by the scan.

Validation

• Re-scanned the tree: zero Ultralytics URLs retain a terminating slash.
• All YAML files parse; prettier@3.8.5 --print-width 120 --check clean on Markdown and YAML.
• All CI checks green (actions including broken-link checks, CodeQL, CLA).

Reviewed all three changed files and the surrounding repository references. The URL edits are otherwise safe and consistent, but one remaining Reddit contact link still uses the redirected host.

• 📝 LOW README.md:10 The Reddit redirect refresh is incomplete: .github/ISSUE_TEMPLATE/config.yml:15 still points to reddit.com/r/ultralytics, so the issue-template contact link continues through the old-host redirect instead of using the canonical www.reddit.com/r/Ultralytics/ destination. Update that remaining occurrence as well. (reddit.com)
