fix(ci): resolve cargo-deny + MSRV + binary smoke failures

[forkwright]

Summary

Three CI failures, two root causes. Both blocking PRs #11 and #12.

Root cause 1 — Cargo.toml multi-line inline tables (breaks MSRV + cargo-deny)

Commit ea46514 (fix: resolve 1 lint violations via local, Qwen3.5-35B) rewrote
rustls, serde, serde_json, and tokio workspace dependencies as multi-line
inline tables to satisfy the TOML/inline-table-too-long kanon lint:

rustls = {
version = "0.23",
default-features = false,
features = [...],}

That syntax is TOML 1.1, supported by cargo only since Rust 1.94.0. hamma's
declared MSRV is 1.85, so the root manifest fails to parse under 1.85's toml
crate:

error: invalid inline table
expected `}`
--> Cargo.toml:48:11
48 | rustls = {
| ^

This failure mode hit both the MSRV (1.85) job and the cargo-deny job (its
bundled parser is also pre-1.1), which is why two seemingly unrelated jobs
failed simultaneously.

standards/TOML.md already prescribes the correct fix: expanded
[workspace.dependencies.X] blocks when an inline table exceeds 80 columns
(lines 87-102), with the explicit note that multi-line inline tables must not
be used in repos whose MSRV predates 1.94 (lines 9-11). The local-model lint
fix violated the standard; this PR restores compliance by converting the four
offending entries to expanded-block form. Trailing newline on Cargo.toml also
restored (it had been dropped by the same auto-fix).

Root cause 2 — unset smoke-test placeholders (breaks binary smoke test)

.github/workflows/rust.yml was generated from the forkwright template and
never customized — the smoke job still ran cargo build --release -p BINARY_CRATE and ./target/release/BINARY_NAME. cargo errored with
package ID specification BINARY_CRATE did not match any packages.

hamma is library-only (dictyon + hamma-core, no [[bin]] targets), so there
is no binary to smoke-test. The job has been removed with an in-place comment
explaining when it should be re-added (once a CLI or daemon crate lands,
pinning real names).
