Subject: [PATCH] fix(daemon): gateway fails to launch on Windows when the
 profile path contains CJK characters (#107751)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

* fix(daemon): write Windows gateway launchers in encodings wscript/cmd can decode

gateway.vbs and gateway.cmd were written as UTF-8 without BOM, but
wscript.exe only reads .vbs as ANSI or UTF-16 LE with BOM and cmd.exe
reads .cmd in the console OEM code page, so installs under CJK profile
paths failed with "file not found" (#107416).

Write .vbs as UTF-16 LE with BOM, write non-ASCII .cmd content in the
system code page when it matches the console page (CJK/Thai locales),
and BOM-sniff plus code-page-fallback on read so launchers from older
installs keep parsing and migrate on refresh. The hidden .vbs launch
path originates from #95480, which addressed console visibility only.

* refactor(daemon): drop unused WindowsLauncherScriptFormat export

The type is only referenced by encodeWindowsLauncherScript's format
parameter within the module, so the export tripped check-deadcode-exports.
Keep it module-local.

* fix(daemon): mark code-page cmd launchers with their encoding for deterministic readback

Prepend an ASCII '@rem openclaw-launcher-encoding=<label>' line to code-page
.cmd launchers and decode by that marker instead of sniffing UTF-8. Some GBK
byte sequences are valid UTF-8 (隆 = C2 A1 reads as ¡), so the old sniff
silently corrupted readback and rejected valid paths; the marker makes decode
deterministic and drops the code-page probe (a PowerShell spawn) from the
frequent readScheduledTaskCommand poll path.

Also fix the representability guard for euc-kr: Node ICU decodes euc-kr as
KS X 1001 only, but Windows code page 949 is cp949/UHC, so the TextDecoder
cross-check false-rejected ~8,800 UHC extension syllables (똠 = 8C 63) that
iconv encodes and cmd.exe reads fine. Verify euc-kr via iconv's own cp949
round-trip; keep TextDecoder for the other five labels.

* fix(infra): write Windows restart helper scripts through the launcher encoder

The update-time restart helper wrote its temp .cmd as raw UTF-8 while
embedding the restart-log path, task name, and task script path, so a CJK
profile path or task name broke the same way as the gateway launchers
(#107416). Route the write through encodeWindowsLauncherScript: ASCII content
stays byte-identical UTF-8, CJK content gets the marked code-page encoding, and
an unrepresentable task name now fails the restart attempt cleanly instead of
writing a script cmd.exe would misread.

* chore(deps): minimize pnpm-lock delta for the iconv-lite promotion

Reset pnpm-lock.yaml to origin/main and re-add only the iconv-lite root
importer entry, dropping the unrelated @types/node peer-context flips and
audio-decode deprecation metadata that a mismatched-toolchain regeneration had
pulled in. The diff vs main is now the three-line importer entry only; the
version already resolves in main's tree via express -> body-parser/raw-body.

* refactor(windows): centralize launcher encoding

* style(windows): format launcher encoding test
