Moves package lsp and cmdutil under tools/lsp/internal/ so the
multicall binary can live at tools/lsp/main.go — same layout as
codeintel and filetools.
Rename ToolInfo.ReadOnly bool → ToolInfo.Scope string with three values:
- "read" — path-scoped read, never conflicts (always parallel)
- "write" — path-scoped write, conflicts on same file path only
- "global" — full serialization barrier, runs alone
Tools declare scope in their .meta file. If unset, inferred from path
arg presence (write if path exists, global otherwise).
This correctly classifies lsp_rename as global (cross-file workspace
edits) despite having a path argument. The path arg in lsp_rename is
a symbol coordinate, not a resource scope.
All .meta files updated: readOnly:true → scope:read,
readOnly:false → scope:global, lsp_rename gets scope:global.
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.
Binaries now read path/line/col (matching the .meta schema the model
sees) instead of file/line/character. Also fix col to be 1-indexed
(matching the schema description) with proper -1 conversion to LSP
0-indexed protocol.
