The legacy @oh-my-pi/pi-coding-agent shim exported the read/bash/grep/find/ls
tool factories but omitted the edit and write ones. pi extensions importing
createEditTool or createWriteTool (e.g. gentle-pi) failed Bun's static export
check during extension validation, blocking omp install.
Added createEditTool/createEditToolDefinition and createWriteTool/
createWriteToolDefinition, mirroring the upstream pi surface and the existing
sibling factories. The unsupported operations seam throws a descriptive error
like createGrepTool does.
Fixes#7094
