docs(readme): rewrite around unmodified pi + extensions (M5–M7) - #2
Merged
Conversation
The README still described the trimmed agent.bundle.js path as the story, the
old lean `api.addTool` plugin API, and listed M5 as "blocked on" the QuickJS
linker crash — all superseded by the merged M5–M7 work.
Rewrites it around what shipped:
- Leads with "run the unmodified pi-coding-agent + its extensions on QuickJS".
- Makes **writing an extension** a first-class section: the default-factory
format (registerTool/on, the execute(toolCallId, input, …) → {content:[…]}
contract), how it's loaded through our oxc loader (no jiti) via pi's
extensionFactories seam, and an honest builtin capability matrix (fs/
child_process/process real; crypto=FNV partial; http/net/tls/… stubs — use
fetch for networking).
- Frames the **Rust `PiRuntime` API** as the embedding surface for downstream
hosts like cat, and distinguishes the two ways to run pi (trimmed core vs. the
full unmodified bundle).
- Updates status to "what works today" and the build/test commands.
Docs only.
