release: dsc 0.8.1

[samifouad]

Version bump only — 9 commits since v0.8.0.

Two additions, both unblocking downstream work

Generic receiver methods (#101, merged as #105). A receiver method can now be declared on a generic type, with the parameter bound by the receiver:

fn (s Signal<T>) get() T
fn (s mut Signal<T>) set(next: T) void

Before this, Signal<T> could hold a value and expose a field but could not have methods — true of the data, false of the interface. This is what deka#771 needs to port ui/* out of hand-written JavaScript.

Bounds are inherited from the struct declaration, so struct Holder<T: Named> plus fn (x Holder<T>) still sees the bound; declaring parameters on both the receiver and the method is now an error rather than silently ambiguous.

bytes member catalog (#92, merged as #106). bytes gets .length, and only .length. RFD 15 lists nine operations but never commits to member-access versus free-function shape, and that call belongs to deka#756 — so this adds what was unambiguous and provably missing, and leaves slice/concat alone rather than shipping language surface ahead of its design.

This one shrinks a ratchet

deka's expected-failures.txt carries unsafe-textencoder-encode and unsafe-uint8array-literal against dsc#92, with the removal condition recorded in the file. Once deka bumps its scripts/dsc-version past this release, those two lines must come out — the runner treats a listed fixture that starts passing as a hard error. The fix has to prove it shipped.

Gate

cargo test --workspace — 34 suites, 0 failures

(First run failed on node is required to execute emitted JavaScript — /usr/local/bin is not on the non-interactive PATH. Environmental, not a product failure, and it was hiding in the tests that execute emitted JS, which are the most valuable ones here.)

After merge

Tag v0.8.1 from main, verify by reading --version off the downloaded artifact, then bump deka's dsc pin.
