fix(delegate-task): Wave 1 - fix polling timeout, resource cleanup, tool restrictions, idle dedup, auth-plugins JSONC, CLI runner hang

- fix(delegate-task): return error on poll timeout instead of silent null
- fix(delegate-task): ensure toast and session cleanup on all error paths with try/finally
- fix(delegate-task): apply agent tool restrictions in sync-prompt-sender
- fix(plugin): add symmetric idle dedup to prevent double hook triggers
- fix(cli): replace regex-based JSONC editing with jsonc-parser in auth-plugins
- fix(cli): abort event stream after completion and restore no-timeout default

All changes verified with tests and typecheck.
