Record progressive refinement as built, and the fit view's two speed-ups

Browse Source 
display-and-extension.md still called FR-DSP-4 absent, and
frame-budget.md ended its reading at "satisfied vacuously". 0.15.0 built
it (refine.rs, the provisional histogram, the fade), so the table row
says so, frame-budget.md gains a note under its FR-DSP-4 section, and the
register gains a status note like FR-RAW-2's and FR-UI-5's.

frame-budget.md also gains a short section with the figures 1dc7b45
(the fit view's gather cached per framing) and d430ec9 (an identity
detail pass dropped) measured, since its fit rows no longer describe the
fused path. They are quoted from those commits, on the machine they name,
and are marked as not re-run here.

| FR-DSP-1 proxy rendering | **Done.** The develop view renders at viewport resolution, not source. |
| FR-DSP-2 tiled computation | **Absent, and §2 now says it should stay that way.** Measured: the fused pass is inside the budget everywhere. See [frame-budget.md](frame-budget.md). |
| FR-DSP-3 interactive latency | **Measured and asserted** for the fused path — `core/dr-gpu/tests/frame_budget.rs`. Missed by one operation, clarity, for the reason recorded as TD-4. |
| FR-DSP-4 progressive refinement | **Absent**, and §4's condition did not fire. Every render is full quality and can afford to be. |
| FR-DSP-4 progressive refinement | **Built** (0.15.0), although §4's condition did not fire on the fused path: a half-resolution draft while a gesture moves, one sharp frame 120 ms after it stops, the histogram dimmed while it lags, and the draft faded out over 150 ms — `ui/dr-ui/src/refine.rs`. See [frame-budget.md](frame-budget.md). |
| FR-DSP-5 zoom and pan | **Done and tagged**, against tests that fail if the behaviour is removed — `core/dr-gpu/tests/zoom_resolution.rs`. `Framing::view` shrinks the sampled region while the render target keeps its size, so zooming *raises* the resolution the pipeline works at. That is FR-DSP-5's requirement, arrived at without tiles. |
| FR-DSP-6 colour management | **Done.** Output space is a parameter of composition. |
| FR-DSP-7 histogram and clipping | **Done**, GPU-side, no per-frame readback. |
