Carry caller-selected target identity separately from launcher selection. Only fully collected ordinary nonzero decode exits represent target refusals; startup, preparation, capture and signal failures retain provider attribution. Reuse one command/preparation output projection for probe and decode errors.
Adapt the target-path correction from PR #3462 (08d3d0d3a0) and extend its producer-boundary classification and regression coverage.
Validation: 131 focused tests in 12 files, final 50 source checks, build, typecheck/lint and docs. Ten regression controls fail on baseline 4844ae812. Twenty-four tiny actual CLI/stdio MCP refusal tasks preserve every projected field except the corrected message/path. Authored launchers only; no real Apktool/JVM or native Windows claim. Heavy stress/profiling remained stopped.
Closes#3340

Admit provider operations through one command resource scope, retain exact process and preparation-helper cleanup capabilities, and bind original failures to their live cleanup leases. Keep unknown recovery capabilities unresolved and fence their workspaces.
Interpret version output at command completion, preserve opaque cancellation and compiler output, and attribute prerequisite failures to the consuming operation. Prepare Darwin ownership outside the short version deadline.
Validation: 106 focused tests across 11 files; final 44 source regressions; build, typecheck/lint, docs and test discovery. Eight new controls fail on the clean baseline. Tiny authored launchers exercise process cleanup and public CLI/stdio MCP; actual Apktool/JVM and native Windows remain unverified. Heavy stress/profiling remained stopped.
Closes#4808
