b6cf2a6b73 fix: prevent Instant duration overflow on Windows (#657) (#664)
* fix: use checked_sub to prevent Instant duration overflow on Windows (#657)

On Windows, Instant starts from system boot time. Subtracting a duration
longer than uptime (e.g., 1 hour on a freshly booted system) panics with
"overflow when subtracting duration from instant", crashing the tokio
worker thread.

Replace `Instant::now() - Duration` with `Instant::now().checked_sub()`
in cost_guard.rs (production), server.rs and session.rs (tests).

* fix: use expect() instead of unwrap_or() in test code

Address PR review: unwrap_or(Instant::now()) silently breaks test
semantics when checked_sub returns None. Using expect() ensures tests
fail explicitly with a clear message about insufficient system uptime.
