fix: isolate native application capture fixtures between runs

test: make real writer ownership and shutdown probes deterministic

fix: preserve native viewport coordinates during candidate resize

test: accept independent restore output after wrapped cmd echo

Follow up the passive readiness experiment for #87; hold both replacement consumers at actual LF boundaries without weakening the original workflow oracle.

测试：在完整记录边界采集替换会话快照

研究：定位 Vim resize 后 MSYS 输入丢失边界 #52

验证：闭合工作区尺寸标记残尾回归 #63

Refs #52. Preserve original fixed-runtime acceptance and publish the licensed source patch, bounded red/green evidence and explicit limitations.

research: 验证 MSYS resize 输入前缀的隔离修补实验

Refs #52, #28, #56. Keep original failures, runtime and backend decisions open.

…st (#56)

Preserve upstream toolchain/dependency identity; require a causal TAEF red,
focused and full adapter green before creating an experimental pair.
Runtime and product acceptance remain unverified.

text=auto still uses native EOL with autocrlf=false; explicitly use LF in
the disposable host. Preserve the failed first CI and unchanged patch SHA.

Keep the exact baseline and dependency versions. A full Git history is
required for the fixed cmark and cli11 trees missing in the shallow clone.

Generate Proxy MIDL headers before hostlib, and preserve the fixed solution's
Types, Buffer, Render and Propsheet build ordering without source changes.

…vidence

Add isolated source pair probes and bounded identity/lifecycle checks. Preserve the original 175-byte workload, native oracle and deadlines. Record the two-grid red-to-green comparison and VT-off controls, with full product and cross-contract limits remaining open.
