_startup_login's background thread and _handle_authenticate's shared the
module-level _login_result_queue with no correlation. Since _startup_login
can now time out at 10s while its thread keeps running (from the previous
fix in this wave), a slow-cold-starting subprocess's first explicit
"Connect to Garmin" call could accidentally dequeue the startup thread's
stale result instead of its own fresh one, orphaning the loser's result to
corrupt a later authenticate/complete_mfa call.
_handle_authenticate and _handle_complete_mfa still correctly share
_login_result_queue -- they're two halves of one explicit, MFA-capable
login flow. _startup_login is a background tokenstore resume with no MFA
involved, so it now uses its own private, function-local queue.Queue()
instead, making cross-contamination structurally impossible.

_startup_login() ran garminconnect's login synchronously with no timeout
before main() ever started reading stdin, so a slow/rate-limited Garmin
login could wedge a user's whole subprocess before it became responsive.
Give it the same background-thread + bounded-10s-timeout shape
_handle_authenticate already uses, with tests for both the fast-success
and timeout paths.
Also refreshes .claude/skills/geniusrun-dev/SKILL.md (still describing
the retired mcp-garmin MCP architecture) and three stale doc comments
(garmin.AuthStatus, config.GarminTokenStoreRoot, mock package doc) left
over from the direct-wrapper migration.

Replaces mcp-garmin's server.py: a JSON-lines subprocess protocol
(authenticate/complete_mfa/call) around garminconnect directly, no MCP.
