Replace nanorouter's regex+decodeURI normalization with the WHATWG URL
parser. Path segments are percent-decoded exactly once in the trie, with
a keep-raw fallback instead of the URIError that crashed v7 on a literal
'%'. Route definitions and locations are NFC-normalized so 'café' matches
regardless of composition. Hash-to-slash rewriting now handles every hash,
not just the first, and state.href is decoded for humans (raw on failure).
Behavior changes from v7: params are no longer double-decoded (%2540 →
'%40', not '@'), and unmatchable encodings fall back to raw segments
instead of silently 404ing.

Same public API as choo 7.1.0 (use/route/start/mount/toString/emit; choo()
callable with or without new, Choo exported). nanobus, nanorouter+wayfarer,
nanolru+component cache, nanoraf, nanohref, nanotiming, document-ready and
scroll-to-anchor are ported into lib/ with per-file attribution; nanoquery
is replaced by URLSearchParams. The v7 node test suite is ported from tape
to node:test and passes unchanged in behavior.
