feat(rust,go,python): geometric split tiering — per-tier doubling byte caps

SplitBuildConfig/TermSplitBuildConfig (and Go SplitBuildConfig/
TermSplitBuildConfig, and the Python builder kwargs) gain byte_cap_max:
when nonzero, tier i's cap is min(byte_cap << i, byte_cap_max) — small
splits at the top of the rank order where queries concentrate, doubling
down the tail so a full worst-case descent pays per-split round-trip
overhead only ~log-many times. 0 keeps the flat single-cap behavior and
every existing manifest byte-identical (the frozen goldens are untouched).

The shared cap_for/capFor arithmetic is pinned cross-language by a new
geometric conformance golden (go/testdata/rrss_geo_build_golden.txt,
asserted byte-for-byte on both sides — a one-off divergence in seal-
boundary placement changes every byte after it), plus a behavioral test
that doubling caps seal fewer splits than the flat base cap. The
build_trigram_splitset / build_term_splitset examples take a cap_max_mb
arg; the OpenAlex retarget (512 MiB base, 8 GiB max → ~18 trigram /
~12 term splits instead of 389/243) runs after the impacts build frees
the box.
