Detailed Description

QUALITY_PLAN G.6 guard: no operator-storage view narrows to `float` outside the allow-list.

`MReal` (`mac_cutcell_mg.hpp`) is the operator storage type -- float unless the build defines
`-DPECLET_FLOW_OPERATOR_DOUBLE` (an `option()` since G.6, was a raw, untested `-DCMAKE_CXX_FLAGS`).
G.6 templated `IbmOverlayT`/`ibmFillEntry`/`ibmModifyStencil` (cut_cell_ibm.hpp) and the geometry
build that feeds them (mac_ibm.hpp, flow_ibm.hpp) on `Real`/`mreal` so a double build carries the
cut-cell overlay in double end to end; this test fails if a NEW hard `(float)` cast or `float`-typed
operator view creeps back in outside the allow-list below, so the next one has to be typed on
`mreal`/`MReal` (or exempted with a stated reason) instead.

A hit is IGNORED when: the line is a pure comment (only prose, no code -- these mention "(float)" in
plain English and are not casts); the whole FILE is allow-listed (an opt-in debug/forensics file
whose float precision is unrelated to operator correctness, or a file whose ghost-projection overlay
is a stated, deferred gap -- see the reasons below); or the line carries a `PRECISION-EXEMPT:`
marker (a deliberate, reasoned exception -- `git grep PRECISION-EXEMPT src/` to read them).
