telemetry

Designed as a minimal library not tied to specific tooling, allowing integration with any monitoring solution, as emphasized in the README's focus on replacing custom instrumentation layers.

Events are emitted as lists of atoms, and handlers can be attached dynamically, providing flexibility for libraries and applications to hook into events without tight coupling.

Includes telemetry:span/3 to uniformly capture start, stop, and exception events for discrete operations, simplifying instrumentation with built-in timing measurements.

Aims to unify telemetry across the Erlang/Elixir ecosystem, reducing fragmentation and enabling interoperability between libraries, as stated in the philosophy section.
