fix(codex-bridge): ship zstd for the agent's Python and refuse to link without it

Codex compresses request bodies with zstd. The agent venv is Python 3.11, which
has no zstd in its standard library, so every Codex request failed on a fresh
install. The matching zstandard build now ships beside the bridge; the status
endpoint reports ok=false when bodies cannot be read, and the IDE then leaves
Codex's config alone. A running bridge from an older build is replaced, and
"Sync now" makes the bridge re-read the IDE session at once.
