Align import handshake ordering and add import capture hooks

[themuffinator]

Motivation

• Mirror the HLIL handshake ordering so the bootstrapped import table is created before the bridge sees the raw bot_import_t and cached update state is reset.
• Allow parity tests to intercept and assert arguments for the shimmed logging and libvar callbacks.
• Ensure the bootstrapped import table includes the same DPrint/BotLibVarSet slots used by the HLIL traces.
• Update comments to document the HLIL-defined sequence so future work preserves parity.

Description

• Added a botlib_import_capture_t capture structure and new APIs BotInterface_SetImportCapture / BotInterface_GetImportCapture in src/botlib/interface/botlib_interface.h and implemented them in botlib_interface.c.
• Instrumented shim/wrapper functions so the following now call capture hooks when present: BotInterface_PrintWrapper, BotInterface_DPrintWrapper, BotInterface_BotLibVarGetWrapper, BotInterface_BotLibVarSetWrapper, and the handshake shims BotInterface_PrintShim, BotInterface_DPrintShim, BotInterface_BotLibVarGetShim, BotInterface_BotLibVarSetShim.
• Reordered the GetBotAPI handshake to: translate bot_import_t into the botlib_import_table_t, call BotInterface_SetImportTable, then Q2Bridge_SetImportTable, then Bridge_ResetCachedUpdates, and set debug-lines afterwards, with an inline comment documenting the HLIL ordering.
• Extended the bootstrapped import table in BotInterface_InitialiseImportTable / BotInterface_BuildImportTable to populate DPrint and BotLibVarSet slots and added comments/headers above new helper functions per repository conventions.

Testing

• No automated tests were executed as part of this change.
