tracks the **active** project only.
Thinking variants keep the effective value in `currentVariant` so existing send
paths capture a stable configuration. The transient `currentVariantSelection`
distinguishes automatic initialization from a picker or shortcut choosing an
explicit override or `Default`; returning to `Default` restores its inherited
effective value. Only explicit overrides are stored in the per-session
selection store.
paths capture a stable configuration. `currentVariantSelection` says where that
value came from: a string is an effort chosen in the picker or by the shortcut,
`null` is an explicit `Default`, and `undefined` is automatic initialization,
which lets the inherited default apply.
`Default` sends no effort at all. It cannot resolve back to the inherited
default: the settings default would take effect again, and the next assistant
reply echoes that effort back as an explicit choice, so the picker jumps off
`Default` one message after the user chose it. For the same reason the
per-session selection store records an explicit `Default` (as `null`) instead of
clearing the entry — a cleared entry is indistinguishable from never having
chosen, and the settings default wins again on the next agent or session switch.
Every write of `currentVariant` writes `currentVariantSelection` with it. They
are one selection; updating only the effective value leaves the picker showing
one effort while sends carry another.
Every loader and mutation takes an explicit directory; omitting it means the
active project, which is what non-Settings callers pass. A load for another
