Misc small fixes (#897)

- **Eliminate `<regex>` usage** — Replaced `std::regex`-based URL parsing in `jupiterbuildstorage.cpp` with manual `string_view` parsing. Added `CXXOPTS_NO_REGEX` to disable regex in cxxopts. Includes comprehensive tests for the new URL parser.
- **Add missing HTTP response codes** — Added `102`, `103`, `203`, `207`, `208`, `226`, `306`, `421`, `425`, `451` to the enum and reason string lookup.
- **Add `ForceColor` support to zen CLI** — Plumbed the `ForceColor` logging option through to the zen client.
- **Add `.clangd` config** — Strips MSVC-specific flags clangd can't handle and suppresses noisy clang-tidy checks.
- **Generic `fmt::formatter` for `ToString`** — Concept-based formatter that auto-formats any type with a free `ToString()` function, removing the need for per-type specializations.
- **Fix OpenSSL dependency** — Changed `zenhorde` to use `openssl3` package on Linux/macOS.
- **Add `<cmath>` include** — Missing include in `hyperloglog.h`.
- **GCC compile fix** — Moved `static constinit` variable inside lambda in `logging.cpp`.
