Traced end-to-end (AGE_DIAG_SETTEX): set-texture slot=G[0x62452] <- query-gfx-object?
(-1 for unregistered CG handles) -> fallback lookup-array-2d(rec[s3]=G[0x3239])=0
because the slot table is never filled: label_125bd (SC0000 0x50f, slots 4..13) is
gated behind the scene-coroutine framework (0x140 coroutine-yield, stubbed). Adds
env-gated VM set-texture/query slot diagnostics + GfxState.IsRegistered.

Root cause (evidence: gfx-log) of the opening-CG grey background: a CG drawn with
(alpha=0, color=white) means 'no tint' = fully opaque, but slice-A conflated the
color alpha with object opacity -> the CG rendered transparent. RenderObject now
carries TintStrength separately from Alpha (opacity); resolution keeps textured
objects opaque. Tests updated to the evidence-based semantics.

Adapted to Task-1 RE: position is a direct V24 set (not ping-pong); the
oscillating channels are src-rect scroll (0x231/0x239) and color glow (0x232).

0x202/0x203 now route through GfxState.SetObjectColor (sets HasColor);
SnapshotVisibleObjects resolves Alpha/Tint/BlendKind. Drops the stale
'alpha deferred' trace stub — alpha/tint is now consumed by the compositor.

The existing trace framework only had a flat text formatter, so every question
became 'dump millions of lines, then grep'. This session that cost a long wrong
detour. Add, all observe-only (parity preserved):
- HistogramTraceSink: execution counts per opcode AND per call-site (script:pc)
with a sample operand. Dumped sorted after the run. This is what instantly
showed the 493k headless 'sleep's are INPUTNAME.BIN:0x1c3 (a name-entry poll
loop), not the opening.
- TraceSinkBase: tracks the frame stack -> attributes each step to its REAL
script (nested call-script frames included) = the 'which script is this pc in?'
answer a bare step trace can't give.
- TextTraceSink: op-filter (--trace-ops sleep,draw-texture,...) + script:pc tags.
- CompositeTraceSink: fan-out (text + histogram + Godot's call-script queue).
- OpcodeTable.ByLabel: mnemonic -> opcode for --trace-ops.
- CLI: --trace-histogram, --trace-ops, robust --trace-file (mkdir -p).
- Godot: --trace-histogram <file> profiles the REAL run (headless flow diverges:
real run to page 1 is 562 steps / 0 sleeps vs headless 2M steps / 493k sleeps).
- Also: --sleep-scale <f> debug knob to slow the paced opening for inspection.
Engine 56/56 (4 new); sweep parity 284/13; Godot builds + dogfooded end-to-end.

Once sleep paces the VM thread, the main-thread compositor's SnapshotVisibleObjects
truly overlaps VM-thread _objects/_registry writes. GetOrCreate/Register/Release were
unlocked -> 'Destination array is not long enough' under concurrent enumeration.
_lock is re-entrant so BindDraw/EraseRange (already locked) stay correct. 52 green.
