Companion to the feat(explorer) commit. Bumps the version and
brings every cross-referencing doc up to v0.9 currency.
- Cargo.toml: version 0.8.0 -> 0.9.0.
- CHANGELOG: 0.9.0 entry covering the explorer export, the
Problem-side metadata additions, the AlgorithmInfo trait, the
pick_a_car example, and the new cookbook recipe.
- README: closing paragraph of the PickACar example points users
at the explorer with a one-call snippet
(`ExplorerExport::from_result(...).with_algorithm_info(...)
.to_file(...)?`). Version snippets bumped 0.8 -> 0.9.
- New cookbook recipe at docs/book/src/cookbook/explorer.md
covering: enabling the serde feature, enriching Problem with
labels/units/decision-schema, the export call, the JSON schema,
and custom decision-type handling.
- SUMMARY.md and cookbook.md link the new recipe.
- migration.md: new "To 0.9" section documenting the additive
changes (purely backwards-compatible upgrade from 0.8.x).
- introduction.md, comparison.md, choosing-an-algorithm.md,
stability.md: version refs bumped 0.8 -> 0.9.
- cookbook/parallel.md, cookbook/async.md: version refs bumped
0.8 -> 0.9.
- getting-started.md: version refs bumped, serde feature
description expanded to mention the explorer module.
- SECURITY.md: supported-versions table moves to 0.9.x.
Initial state from `cargo new --lib` plus the technical design spec at
docs/heuropt_tech_design_spec.md, which is the source of truth for the
crate's public API and v1 acceptance criteria.
