Remove emojis from documentation and CLI output

[Copilot]

Removes emojis from README and CLI to adopt a more professional tone suitable for enterprise environments.

Changes

• README.md: Removed emojis from section headers (✨ Features → Features, 📦 Installation → Installation, etc.)
• README.md: Replaced emoji checkmarks in comparison table with plain text (✅/❌ → Yes/No)
• README.md: Removed emojis from feature list bullet points
• src/cli/index.ts: Removed checkmark emoji from success message (✓ Cloned to → Cloned to)

Before:

logger.success(`✓ Cloned to ${result.destination}`)

After:

logger.success(`Cloned to ${result.destination}`)

No functional changes. Source code already contained no emojis.

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• google.com
  • Triggering command: /usr/local/bin/node /usr/local/bin/node /home/REDACTED/work/gitly/gitly/node_modules/jest-worker/build/workers/processChild.js (dns block)
• https://api.github.com/repos/lukeed/gittar/commits/master
  • Triggering command: /usr/local/bin/node /usr/local/bin/node /home/REDACTED/work/gitly/gitly/node_modules/jest-worker/build/workers/processChild.js (http block)
• https://api.github.com/repos/nonexistent-user-12345/nonexistent-repo-67890/commits/master
  • Triggering command: /usr/local/bin/node /usr/local/bin/node /home/REDACTED/work/gitly/gitly/node_modules/jest-worker/build/workers/processChild.js (http block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)

Original prompt

Make it less emoji and fruity on the readme and if the code has that same feel please remove it. You are a senior dev
