Address Phase C review (C-1, C-2): make CallResolver.plan's SelectedFunc the single shared call author consumed by the lower-call sites instead of each re-resolving; route free-fn value-receiver UFCS through the selector in plan so plan typing and lowering pick the same author under a flat same-name collision. Adds regression 0740-modules-flat-same-name-ufcs-typing. Salvaged from a worker killed at the wall during its final gate step; manager verified the gate at ground truth (zig build test exit 0; run_examples 476/0 with 0722-0735 + 0740 ok; m3te ios-sim exit 0).

// Regression (issue 0102, Phase C): value-receiver free-function UFCS under a
|
|
// flat same-name collision must be TYPED as the author lowering dispatches.
|
|
// a.sx (imported first → first-wins winner) authors `tag -> string`; b.sx
|
|
// authors its OWN `tag -> s64`. In b.sx, `v.tag()` dispatches b.tag (s64), but
|
|
// before the fix the call PLAN typed it as a.tag (string, first-wins) — so the
|
|
// pack-fn `print` boxed the raw s64 110 as a string pointer and dereferenced
|
|
// 0x6e → segfault. `CallResolver.plan` now selects the SAME author the lowering
|
|
// call-path binds, so plan-typing and dispatch can't disagree (fix-0102 F2).
