text: render captured unknown fields, tolerate SGROUP in skip

Two changes close the proto3 text-format conformance suite:

  1. `wire.skip_field` learns SGROUP/EGROUP. Wire 3 recurses through
     inner tags until a matching EGROUP, with field_id checked against
     the SGROUP's id. Callers (codec.lua, lazy.lua, wkt.lua, generated
     full-mode `_pb.lua`) now pass the tag's field_id so groups inside
     unknown-field skips don't error.

  2. `pb.text.encode` walks the captured `_unknown_fields` buffer when
     `opts.print_unknown_fields=true` and emits each entry in
     TextFormat numeric-field form:
       VARINT  -> "<id>: <uint64>"
       I64/I32 -> "<id>: 0x<hex>"
       LEN     -> speculative "<id> { <recurse> }"; rolls back to
                  byte-string form if the inner bytes don't parse as a
                  sub-message
       SGROUP  -> "<id> { <recurse> }" through matching EGROUP

`cmd/conformance/core.lua` threads `req.print_unknown_fields` into
`pb.text.encode` so `_Drop` tests drop unknowns and `_Print` tests
render them.

Conformance: text-format suite goes from 2 ✓ / 6 expected fails to
8 ✓ / 0 expected fails. All eight regression tests in
`conformance_test.lua` (one per upstream test, plus the fixed field-1011
tag bytes that were miscomputed earlier) now assert the target output.
