fix: provider() unicode-digit crash + phantom() short-value false-mask (v0.3.2)

Browse Source 
provider() used str.isdigit(), which accepts unicode digit lookalikes (e.g. superscript
²) that int() can't parse, crashing on digit-only-looking input; _digits() now filters
on isdecimal()+isascii() so only real ASCII digits pass through. phantom() revealed the
entire value for len <= 10 while still looking masked (first6+last4 fully covers or
double-covers short strings); those now fully mask instead. Also compresses several
essay-length docstrings (retry, masking, paths) to a line plus the real nuance, with
zero behavior change, and bumps the README install pin.

The base install pulls **nothing** (stdlib). Only `commons[addr]` adds `aiohttp`, and
only for the geo lookups — the pure `commons.addr.ip` utilities ship in base.
