Add scripts/cfw_install_jb_post.sh — an idempotent SSH-based finalizer to complete JB bootstrap on a normally-booted vphone (creates /var/jb symlink, fixes ownership, runs prep_bootstrap, creates markers, installs Sileo, and runs apt; requires sshpass). Add Makefile help, .PHONY and target cfw_install_jb_finalize to invoke the script. Remove host-side IPA signing/installing and related UI: delete VPhoneSigner, VPhoneIPAInstaller, VPhoneMenuInstall and remove signer/ipaInstaller fields and menu items/callbacks from the vphone-cli UI (also removed the DevMode enable WIP flow). Misc: minor table/formatting tweaks in AGENTS.md and research docs.
- Replace Python cfw_inject_dylib.py with tyilo/insert_dylib (built by setup_tools)
- Use --weak flag for LC_LOAD_WEAK_DYLIB injection (avoids crash on missing dylib)
- Preserve original launchd entitlements on re-sign (fixes "operation not permitted")
- Deploy dylibs from pre-built basebin payload instead of building from source
- Remove launchdhook, systemhook, treblehook sources (no longer needed)
- Print GDB debug stub port after VM starts
- Cleanup: remove test scripts, rename patch comparison doc
