Tools no longer need to be co-located in $OLLIE_TOOLS_PATH. The .meta
sidecar can specify a cmd field pointing to any executable:
- Absolute path: use directly
- Bare name: resolve via $PATH
Resolution order: OLLIE_TOOLS_PATH/<name> → meta.cmd → PATH lookup.
Local wrappers always win, enabling simplified interfaces over complex
system binaries.
Rewrites doc/WRITING_TOOLS.md to document the plugin model: any
executable + .meta = tool, no source tree integration required.
