move LSP .meta files to live alongside their Go code

Each lsp_*.meta now lives in tools/lsp/cmd/<name>/ alongside
main.go, rather than in data/tools/. The lsp-tools just target
was updated to install both the binary and its .meta sidecar.

AGENTS.md updated to document the pattern for compiled tools.

 Both paths produce the same result: an executable + `.meta` in `$OLLIE_TOOLS_PATH`.
 The registry doesn't distinguish between scripts and binaries.
