v0.10.0

Integrates three work units, verified green via nix flake check (667 tests) and CI.

Fixes — runtime correctness

• Cleanup hooks (after-each/after-all) always run via unwind-protect, and condition handling is widened to serious-condition so SBCL platform timeouts (bare serious conditions, not errors) still reach cleanup.
• --bail only consumes a following token when it parses as a valid bail value; supports inline --bail=N.
• Isolated output is read via uiop:read-file-string (char-accurate for multibyte content).
• gen-such-that validates that its predicate is a function.
• :random test ordering computes each label hash once (decorate-sort-undecorate).

Performance

• Strict-empty-batch fast path in collection (skips the CPS walk for trivially-empty suites).
• Single-pass list+tail cloning, incremental stable hashing, one-shot suite lineage.
• S-expression reporters bind *print-pretty* to nil for stable, single-line machine output.
• Adds a benchmarking harness under benchmarks/.

Refactor

• Split the largest source and test files into focused, single-responsibility modules with dependency-ordered ASDF wiring.
