…opup Add a chry_dap_webusb_popup_enabled() weak hook in dap_main.c that controls the iLandingPage byte of the WebUSB BOS capability, so the browser landing page popup can be turned off at runtime. HSLink-Pro stores it as webusb_popup in the settings JSON (default enabled) and exposes it via the settings/get_setting HID commands.
📝 WalkthroughWalkthroughThe change adds CJTAG-only DAP support and configurable WebUSB popup behavior. HSLink-Pro stores the popup setting, exposes it through HID configuration, and applies it to the BOS descriptor during DAP initialization. ChangesCJTAG support

Guard the WebUSB descriptor write with USBD_WEBUSB_ENABLE.
When USBD_WEBUSB_ENABLE is 0, chry_dap_init() still calls chry_dap_webusb_popup_apply(), but the BOS descriptor has no WebUSB iLandingPage byte. Offset 28 then targets the remaining WinUSB capability and overwrites its dwWindowsVersion field.

Re-enumerate USB after changing webusb_popup
When HID changes webusb_popup on an enumerated HSLink-Pro, chry_dap_webusb_popup_apply() only patches USBD_BinaryObjectStoreDescriptor. The host can continue using the BOS descriptor read during enumeration, so the new popup preference may not take effect until USB re-enumerates. Trigger re-enumeration or provide a documented restart path.

Provide CJTAG chain storage and bound the configured count.
When DAP_CJTAG != 0 and DAP_JTAG_DEV_CNT == 0, DAP.h omits the IR arrays, but DAP_JTAG_Configure still accesses them under the same CJTAG condition. The build therefore fails. When storage exists, the function also uses the host-supplied count without checking DAP_JTAG_DEV_CNT, so an oversized count writes beyond the arrays.
Require non-zero chain storage for CJTAG and reject counts greater than DAP_JTAG_DEV_CNT before the loops.
