v0.5.3

CLI, Modes & Matrix

• feat: support mode fan-out behavior consistently across ast build, ast run, and ast test.
• feat: when no --mode is provided and modes are configured, run using configured modes.
• feat: add matrix-style per-file output with mode-aware timing:
  • non-verbose: average time
  • verbose: per-mode times.
• feat: add real-time matrix line updates in the default reporter and normalize timing precision to one decimal.
• feat: support comma-separated bare selectors (for example ast test box,custom,generics,string) across build/run/test selectors.

Config Merge & Env Behavior

• fix: apply mode config as field-level merge over base config instead of replacing entire sections.
• fix: merge buildOptions.args between base config and mode config.
• fix: pass config env variables to both build and run processes for mode execution.

Build Pipeline & Feature Flags

• feat: include the exact build command in build failure output.
• feat: allow buildOptions.cmd to override default command generation while still appending user build args.
• feat: support CLI feature toggles:
  • --enable coverage / --disable coverage
  • --enable try-as / --disable try-as.

Reporter & Summaries

• fix: move mode summary rendering into the default reporter (via run-complete event payload).
• feat: include modeSummary for single-mode runs.
• feat: include mode and snapshot totals in final summary output.
• fix: --clean output now behaves as non-TTY in default reporter:
  • no in-place line editing,
  • no suite expand/collapse logs,
  • final per-file verdict lines only.

Coverage & Transform

• fix: ignore AssemblyScript builtin/compiler helper calls during coverage instrumentation (including isString, changetype<T>, idof<T>, sizeof<T>).
• fix: mock transform now collects mocked import targets across sources so WASI mock imports are rewritten reliably (resolves import-shape runtime failures).
