refactor: reorganize directory structure into src/

Move all source code directories into src/ for cleaner project structure: - pages/, components/, utils/, config/, providers/, types/, lib/, assets/, entrypoints/ → src/ - Use WXT srcDir config to resolve @/ alias to src/ - Update tsconfig, vitest, eslint, tailwind configs - Remove scattered README.md files from subdirectories - Update documentation (AGENTS.md, CODING_STANDARDS.md, README.md) - Fix pre-existing lint error in RouterProvider.tsx Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>
