Add logfire to Logging section - #3353

Project

logfire

Checklist

• I read CONTRIBUTING.md - awesome-python is a shortlist, not a catalog
• One project per PR
• PR title format: Add project-name
• Entry format: - [pypi-name](https://github.com/owner/repo) - Description ending with period.
• Display name is the PyPI package name
• Placed in an existing use case (new sections and subcategories are maintainer-only)
• Meets all Quality Requirements: active, stable, documented, at least 1 month old

Which Tier

Pick one:

• Obvious choice - a tool an experienced Python developer would name when asked "what do I use for this?"
• Challenger - not yet the obvious choice, but a credible successor to one. Give adoption-trajectory evidence, not popularity alone.

Explain: logfire is the official observability and structured logging platform from the creators of Pydantic. It is rapidly becoming the standard for tracing, metrics, and logging in modern Python and AI/LLM applications.

Displacement

If the use case is at its cap, name the entry your project replaces and argue that yours does that entry's job better. One in, one out.

Not applicable. The Logging section is not at capacity, and logfire provides a distinct, official Pydantic-backed solution for structured observability that complements existing tools.
