* fix(cli): resolve local plugin directories from the caller's cwd
Relative plugin sources were sent unchanged, so a daemon started elsewhere inspected the wrong directory. Resolve directory sources and expand the caller's home before sending, preserving subdirectory suffixes and managed source identifiers.
* fix(cli): preserve absolute plugin paths across host platforms
A remote daemon may use another operating system. Recognize absolute POSIX and Windows directory sources before resolving relative paths on the CLI host.
