fix(deps): bump the rdb fork to stop a print to stdout - #199
iq decodes Redis RDB dumps with github.com/zsltg/rdb, its fork of github.com/hdt3213/rdb. The decoder printed unknown module type: <name>,will skip to process stdout for every module entry whose type has no handler. iq uses stdout as its data channel and, under iq mcp, as the JSON-RPC stream, so one such line corrupts both. A dump from any Redis server that runs modules triggers it, and so does a 45-byte crafted file. A security audit found this.
The fork branch zsltg-module-path now has commit 8defd17, which removes the print and adds a test in the fork. iq imports only encoder, model and parser from the fork, and no other print runs on that path.
This PR moves the pin from v1.3.3-0.20261007154853-79442de87f28 to v1.3.3-0.20261027142827-8defd17752d8. go.sum changes only for that module.
New test TestRDBSourceUnknownModuleWritesNothingToStdout in drivers/file decodes dumps with an unknown module aux entry (opcode 247), a module value (type 7), and both. It captures stdout and requires that nothing is written and that the other records stay intact. It fails on the old pin and passes on the new one.
The fork note in go.mod and DEVELOPMENT.md now names the second reason for the fork. Upstream needs this fix too before iq can switch back.

The rdb fork printed "unknown module type: <name>,will skip" to stdout
for each module entry that has no handler. iq uses stdout for data and,
under iq mcp, for the JSON-RPC stream. The print corrupted both.
The fork head now removes the print. Update the pin to commit
8defd17752d8 of the zsltg-module-path branch.
Add a test in drivers/file. It decodes a dump with unknown module aux
and value entries. It makes sure that nothing goes to stdout and that
the other records stay intact.
Update the fork note in go.mod and DEVELOPMENT.md. The fork now has two
reasons. Upstream needs both fixes before iq can switch back.

Walkthrough
The RDB dependency is updated to a newer fork revision. New tests check stdout and key preservation when decoding dumps with unknown module auxiliary data or values. Documentation describes the fork’s stdout behavior and the conditions for returning to upstream.
Changes: RDB module output
Layer / File(s)
Summary
Update and verify RDB decoding go.mod, drivers/file/rdb_module_stdout_test.go, DEVELOPMENT.md
The RDB dependency is updated, and the fork notes describe its suppression of stdout output for unknown module types. Tests cover auxiliary data, module values, and both together. They assert that decoding returns no error, writes nothing to stdout, and preserves keys a and c.
The dependency update targets unwanted stdout output. No merge-blocking risk is established.

collect each surrounding record’s value alongside its key, then assert that the
records retain the fixture values for “a” and “c” while preserving the existing

The test checked only the keys of the records around the unknown
module entries. It now also checks their values, so a decode that
keeps the keys but loses the values fails.

goreleaser runs as many tasks at once as GOMAXPROCS, so the runner
built four targets in parallel. On 2026-10-27 the release-snapshot job
of #199 was killed three times during that build step, with a runner
shutdown signal. The last success was on 2026-10-26.
Pass --parallelism=2 to goreleaser in the release-snapshot job and in
the release workflow, so both build two targets at a time.
