ci: disable carryforward flags to flush stale data

[xdustinface]

Stale carryforward flags from a previous per-crate flag config are inflating the session count and causing premature codecov status checks. Disabling carryforward temporarily so a clean CI run establishes fresh baseline data for the current flags.

Poem

🐰 A tiny flag doth turn from green to nay,
Configuration dance in subtle way,
Carryforward rests, no more shall roam,
The codecov config finds its home!
