The next dev-cycle tag v0.26.dev0 is already on main, so setuptools_scm derives the version of normal git builds straight from the tag as 0.26.devN (verified: it resolves to 0.26.dev117 on this branch). This commit does not change those builds. It only updates the versions setuptools_scm does not produce: the hardcoded fallbacks used when there is no git metadata to read, e.g. sdists or bare source checkouts (`TVM_VERSION` in `include/tvm/runtime/base.h`, `fallback_version` in `pyproject.toml`, `__version__` in `python/tvm/libinfo.py`), plus the hand-managed tvmjs npm version (`web/package.json`, `web/package-lock.json`). All move from the old 0.25 cycle to 0.26.
