fix: Live Share codes are Crockford base32, like 7KQ-4MZ-9XR, in place of words

Two random words made codes like "678-scary-virus". A code is now nine symbols of Crockford base32 (0-9 and A-Z without I, L, O and U), shown in threes: two numbering the relay's room (it numbers 1 to 999, which two symbols hold), six of secret, 30 bits, and a check symbol, the symbols weighted 1 to 8 modulo 31, which refuses a mistyped symbol or two swapped before it spends one of the relay's tries. Reading ignores case, hyphens and spaces and takes I and L for 1, O for 0. With five tries before a code burns, a guess at one code succeeds with odds 5 in 2^30, about 1 in 215 million; every burn draws a new secret, and the relay's lockout leaves one address about ten tries an hour. The relay is unchanged: rooms are still code-<n>. A word code and a new code each read as malformed on the other version, before any network. Assisted-by: claude-opus-5.5
