This is a major rework focusing on token efficiency, cost, and speed.
We are *removing* a lot of tools, because i think modern models do
better without them.
tldr; we are moving down to just four tools
shell: the usual run a command tool with large output handling.
edit: standard find/replace but terse output
write: create or overwrite a file, also terse output
tree: a portable version of the tree command with line number counts
This also moves the tools out of the mcp cli and into platform, to save
some small but non-zero overhead and to make it easier to terminate long
running shell commands
