v2.1.140：エージェントツールのマッチング改善と不具合修正

What's changed

• Improved Agent tool subagent_type matching to accept case- and separator-insensitive values (e.g. "Code Reviewer" resolves to code-reviewer)

• Updated agent color palette

• Fixed /goal silently hanging when disableAllHooks or allowManagedHooksOnly is set — now shows a clear message instead of an indicator that never resolves

• Fixed a regression in settings hot-reload where symlinked settings files caused misattributed change events and spurious ConfigChange hooks

• Fixed claude --bg failing with "connection dropped mid-request" when the background service was about to idle-exit

• Fixed background service startup failing on machines with enterprise endpoint security by allowing more time

• Fixed remote managed settings not retrying on 401 — now retries once with a force-refreshed token

• Fixed managed extraKnownMarketplaces auto-update policy not being persisted to known_marketplaces.json

• Fixed /loop scheduling redundant wakeups to poll for background tasks that already notify on completion

• Fixed a recurring event-loop stall on Windows when a missing executable (e.g. gh) triggered synchronous where.exe re-spawns on every check

• Fixed Read tool calls failing validation when offset is passed as a whitespace-padded or +-prefixed string

• Fixed native terminal cursor not staying at the input caret when the terminal loses focus

• Plugins now warn when a default component folder (e.g. commands/) is silently ignored because plugin.json sets the matching key. Shown in /doctor, claude plugin list, and /plugin.
