@yao-pkg/pkg's SEA bootstrap extracts native addons from the VFS into a
per-user cache ($PKG_NATIVE_CACHE_PATH/pkg/<sha256>/) with plain
writeFileSync, so concurrent first starts of the same executable truncate
files another process has already mapped: SIGBUS on Linux, "Library not
loaded" for sharp's libvips on macOS. Extend the existing pnpm patch so the
three write sites go through a same-directory temporary file and
renameSync; a cache path is then either absent or complete, every process
finishes its own copy pass before it loads, and identical content makes
concurrent renames harmless without a lock. Cache location, hash keying,
and per-file comparison are unchanged. The single-exe Agent Note records
the decision and the measured before/after runs.
Closes#4664
@yao-pkg/pkg's SEA bootstrap rewrites child_process commands named node --
including the string after a -c flag, exactly the Bash tool's bash -c form --
to the executable itself and stamps PKG_EXECPATH into every child
environment, so a model-issued 'node --version' silently booted the dsh CLI
instead of the machine's Node. Pin the packager as an exact root
devDependency invoked through pnpm exec and patch out the single
patchChildProcess call from the SEA bootstrap bundle; packaged children now
resolve node through PATH like any other process. The third-party notices
drop the build-time tools section: the packager is now a declared, patched
devDependency, so the manifest and patch tiers disclose it.
Consolidates the personal dsh-tui customizations (module split into
components/session/extension, prompt template + running-glyph indicator,
copyable transcript, tool-card headers, timing placement, XML tool output,
status/footer rework) and ports upstream's model reasoning-effort selector
(Shift+Tab effort cycling, effort-aware /model, footer, and /status) onto
the personal module layout.
