Add say-it: pronunciation dictionary for project names

[anzy-renlab-ai]

Adds say-it — a community-maintained dictionary of how engineers actually pronounce project / product / programmer-jargon names, wrapped in a tiny Bash CLI that uses macOS `say`.

Fits in For Developers (development-tool category) — it solves the specific pain of mispronouncing project names in standups / conference talks. The CLI plays each reading three times with audible alternate chains for contested words (`GIF` → "jif. jif. jif. or: gif.").

• 🌐 Live: https://pronounce.renlab.ai
• 230+ entries (kubectl, nginx, JSON, GIF, Pydantic, Knative, LaTeX, ...), each tagged with a confidence level and source URL where one exists
• MIT, zero deps beyond `say` and `afplay` (both shipped with macOS)
• Ships with a Claude Code skill that turns "how do you pronounce X?" prompts into audio + a source URL

Closing in favor of #710, which has a more current and informative description of the project.
