* feat(setup): add native Pi client support
* fix(setup): isolate invalid Pi agent directory overrides
Keep malformed Pi path evidence on its client entry so unrelated selected clients can complete setup and doctor. Preserve explicit Pi rejection and block filesystem operations rather than falling back to another directory.
* fix(setup): parse Pi configuration as strict JSON
Pi's installed MCP loader reads mcp.json with a bare JSON.parse and no
BOM tolerance, so comments, trailing commas, a BOM, or an empty existing
file yield loader errors and no servers. Parsing the Pi dialect with
objectSchema.parse(JSON.parse(text)) before the shared empty/JSONC
shortcut rejects those files at every mutation boundary instead of
reporting configured registrations Pi cannot load. A missing file still
initializes a fresh strict-JSON document, other dialects keep their
JSONC/BOM/empty tolerance, and malformed files are never rewritten.
