roundTrip now wraps the returned error with the new ErrNotFound
sentinel whenever the wrapper's response set not_found (Task 1),
letting any Client method's caller distinguish a definitive 404 from
a transient failure via errors.Is, regardless of which garminconnect
method was called.
GetActivities/GetActivitySplits/GetActivityDetails/GetWorkoutByID now send
{"cmd":"call","params":{"method":...,"args":...}} instead of named MCP
tools. subprocessClient fully implements Client.

Structured {status, message} responses replace the old string
pattern-matching (parseAuthResult) -- both sides of the protocol are now
owned by this repo, so there's no need to guess at phrasing anymore.

ensureStarted's stderr-copy goroutine could still be mid-Read when close()
called cmd.Wait(), which os/exec's StderrPipe docs call out as incorrect
and can truncate/garble trailing stderr diagnostics or surface a spurious
"file already closed" error. close() now waits on a stderrDone channel,
closed by the copy goroutine once it hits EOF (unblocked by killing the
process), before calling Wait.

subprocessClient spawns the embedded pyscript/wrapper.py over os/exec and
speaks newline-delimited JSON instead of MCP. Auth/data methods land in
follow-up commits; this is the transport + lifecycle plumbing only.
