- Removed TactilityC, moved its symbols to existing modules and several new ones (pthread-module, c-symbols-module, cpp-symbols-module, posix-symbols-module, freertos-module). - Removed Firmware subproject and moved main() into Tactility subproject. - Strengthened application archive, path, version, stack-size, and device validation. - Moved symbol resolution for elf_loader to app-esp32-module. - Improved `struct Module` declarations and made module and symbol definitions in modules more consistent. - Removed old http download code from Tactility subproject. - Rename app-module's source files for consistency. - Add missing pthread symbols. - Kernel module symbols are now resolvable on all platforms.
