Subject: [PATCH 1/2] build(deps): remove unused dependencies

Remove dependencies confirmed unused by cargo-machete analysis,
as identified in the dependency audit (discussion #8, issue #29).

mujina-miner:
  - sha2: bitcoin crate provides SHA-256 via bitcoin_hashes
  - hyper (direct): still available transitively via axum/reqwest
  - modular-bitfield: no usage in source

mujina-dissect:
  - hex: no usage in source
  - thiserror: no usage in source
  - tracing: no usage in source (tracing-subscriber retained)

Also removes sha2, hyper, and modular-bitfield from workspace
dependencies as they are no longer referenced by any member.

Eliminates ~15 exclusive transitive crates.

Refs: #29

Subject: [PATCH 2/2] build(deps): gate linux-only tracing deps to linux target

Move tracing-journald from unconditional [dependencies] to
[target.'cfg(target_os = "linux")'.dependencies] so it is not
compiled on macOS.

Gate the corresponding imports in tracing.rs (env,
tracing_journald, prelude::*) behind cfg(target_os = "linux")
to match, fixing unused-import warnings on macOS builds.
