Brotli: download ældre versioner

SECURITY
- CVE-2026-111497: out-of-bounds write permits remote code execution

SECURITY
- python: added Decompressor::can_accept_more_data method and optional
output_buffer_limit argument Decompressor::process;
that allows mitigation of unexpectedly large output;
reported by Charles Chan (https://github.com/charleswhchan)
Added
- decoder / encoder: added static initialization to reduce binary size
- python: allow limiting decoder output (see SECURITY section)
- CLI: brcat alias; allow decoding concatenated brotli streams
- kt: pure Kotlin decoder
- cgo: support "raw" dictionaries
- build: Bazel modules
Removed
- java: dropped finalize() for native entities
Fixed
- java: in compress pass correct length to native encoder
Improved
- build: install man pages
- build: updated / fixed / refined Bazel buildfiles
- encoder: faster encoding
- cgo: link via pkg-config
- python: modernize extension / allow multi-phase module initialization
Changed
- decoder / encoder: static tables use "small" model (allows 2GiB+ binaries)
