Stratus3D/eflambe

eFlambe is an Erlang and Elixir profiling tool that generates runtime flamegraphs without requiring source code modifications. It dynamically injects tracing code using the meck library to capture function executions and outputs the data in Brendan Gregg or SVG formats for visualization. The system manages trace state through a dedicated server and tracer, providing a public API for capturing and applying traces to applications.

The documentation now includes a visual architecture diagram (generated from Graphviz) illustrating the relationships between core components like the public API, supervision tree, and output formatters, alongside a new overview document that introduces the tool's purpose and key features.

This commit introduces the eFlambé project, an Erlang/Elixir tool for rapid, runtime flamegraph generation without source code modification. It establishes the project structure with Apache 2.0 licensing, CI workflows, and documentation. The tool supports outputting trace data in Brendan Gregg and SVG formats, allows users to specify output directories, and integrates with Speedscope or Hotspot for visualization. It relies on the meck library for mocking modules to inject profiling code dynamically.

This commit introduces the eflambe application, a tool for rapid profiling of Erlang and Elixir applications. It provides public API functions \eflambe:capture/1-3\ and \eflambe:apply/1-2\ to trace function executions and generate flamegraphs. The system includes a tracer (\eflambe\_tracer\) and server (\eflambe\_server\) to manage trace state, along with output formatters for Brendan Gregg's collapsed stack format (\eflambe\_brendan\_gregg\) and SVG graphics (\eflambe\_svg\). It also integrates with the \meck\ library for mocking and supports options for output directories and automatic viewer opening.

Added comprehensive Common Test suites (eflambe\_SUITE, eflambe\_server\_SUITE, eflambe\_tracer\_SUITE, eflambe\_meck\_SUITE) and helper modules (arithmetic, helloworld) to verify the eflambe profiling library. The tests cover core functionality including function capture and apply operations, integration with the eflambe\_server gen\_server for trace management, tracer initialization, and the meck-based mocking shim logic, ensuring happy paths and error handling for features like multiple captures and Brendan Gregg format output.
