📄 Description

Summary

Fixes #5616 by reverting to upstream behavior where execFileOutput waits naturally for inherited-pipe descendants to close their output streams, rather than forcibly cutting off readers.

Problem and expected behavior

When a stoppable execFileOutput command exits while a descendant keeps inherited stdout/stderr open, the original PR #5587 approach of cutting off readers after stop grace was fundamentally incompatible with upstream expectations. The upstream test "keeps scratch files until an inherited-pipe descendant closes them" expects NO reader destruction.

Change and scope

Final approach (matching upstream):

Removed reader destruction after grace timeout - execFileOutput now waits naturally for all inherited-pipe descendants to close their output streams
Removed outputReadersCutOff and outputTruncated tracking (no longer needed)
Removed BootstrapProcessTable.ts and CompilerProcessFamilySettlement.ts (no longer needed)
Simplified cleanup blocks in DarwinProcessRunTokenReader.ts and NativeUiHelperRuntime.ts

Follow the contribution scope. Not applicable — lifecycle fix within existing process boundaries.

Contract and boundary impact

Semantic owner and earliest changed stage: execFileOutput / process preparation cleanup.
Contribution scope fit and linked maintainer decision: not applicable.
CLI and MCP/tool-catalog contract: none.
Provider, bridge, target-format, or platform compatibility: Darwin helper compilation path.
Evidence, artifact, provenance, or reconstruction contract: none.
Target selection, authority, upstream behavior, and cleanup details (if applicable): matches upstream behavior of waiting for inherited-pipe descendants.
Generated metadata impact: none.

Expected effects:

Read existing files or captured data.
Launch or attach to a process.
Inject instrumentation or run scripts/code.
Change process memory, registers, files, or configuration.
Contact network services.
Recover protected code or work around protections.
Documentation or usability only; no target interaction.
Not sure yet; investigation or maintainer guidance needed.

Evidence and regression coverage

Tests added or updated: removed test expecting outputReadersCutOff behavior; removed test for family-exit waiting
All upstream tests now pass, including critical test "keeps scratch files until an inherited-pipe descendant closes them"
Verified on Node 24.18.0, macOS arm64

Validation performed

npx vitest run src/process/ExecFileOutput.test.ts — 31/31 passed
npx vitest run tests/process-global/darwinCompilerCleanup.test.ts — 14/14 passed

Compatibility, safety, and release

Breaking changes or migration steps: none.
Real Hopper/Ghidra, browser, or OS coverage: not run; focused process-global tests on macOS.
Package or release metadata impact: none.
Security, privacy, process, or containment review: not applicable.
