Closes session-inbox-monitor-stophook-utf8-fix. Cyrillic message bodies arrived
as mojibake when force-delivered via the Stop-hook block reason.
Root cause: ~/.claude/hooks/stop-dispatcher.ps1 reads bodies with -Encoding UTF8
(fine) but did NOT set [Console]::OutputEncoding, so ConvertTo-Json to stdout
under a harness-spawned redirected pipe (WinPS 5.1) emitted in OEM cp866.
Fix applied to the machine-local hook (not in git): set
[Console]::OutputEncoding/$OutputEncoding = UTF8 at the top. In-situ RED->GREEN
verified through the real Stop-hook path: a Cyrillic pangram that previously came
back as mojibake now delivers clean; no-loop holds.
Repo changes: SKILL.md Failure modes documents the encoding contract for inbox
writers (no-BOM UTF-8 LF; WriteAllText, not Set-Content -Encoding utf8 which BOMs
under 5.1); bump 0.2.0 -> 0.2.1 PATCH. stop-dispatcher.ps1 multi-machine
propagation is the workshop setup's concern (notified).
