chore: prepare 0.1.0 for crates.io publish

Add LICENSE-MIT and LICENSE-APACHE at workspace root and in each member package so the dual MIT OR Apache-2.0 license ships in the published .crate.

Fill in publish metadata (authors, repository, homepage, readme, keywords, categories) across the workspace and both members.

Add CHANGELOG.md with a 0.1.0 initial release entry.

Fix clippy lints: unused enumerate index, collapsible if, Default impls for TimerTable, SimRadio, and Ctx, use RangeInclusive::contains.

Exclude examples/microwave_tui.rs from the published package. The file stays in-tree but has known unawaited async log futures that need a dedicated pass before it ships.

Apply cargo fmt across the workspace.
