Closes #308, Closes #310, Closes #311, Closes #312, Closes #321, Closes #327, Closes #329, Closes #331, Closes #332, Closes #333, Closes #334

Closes #308

Add dedicated spec test files for: tar, gzip, file, less, stat, watch,
env, printenv, history, df, du, xargs, tee, comm, wait, strings.

Tests cover both positive behavior and negative/error cases.

Closes #310

Add unit tests for:
- parser/ast.rs: AST node construction (already had coverage, verified)
- interpreter/state.rs: ExecResult, ControlFlow constructors and methods
- fs/backend.rs: FsBackend trait defaults, FsUsage
- fs/traits.rs: FileType, Metadata, DirEntry, error constructors

https://claude.ai/code/session_012MkWqsq7cuwfd3RpsF5RCT
Closes #311

Add unit tests for: test/[, expr, dirstack (pushd/popd/dirs),
seq, flow (true/false/exit/break/continue/return), read.

Tests cover both positive behavior and negative/error cases.

…rection

Closes #332

- Levenshtein distance typo detection against known builtins/functions/aliases
- Hint table for unavailable sandbox commands (pip, sudo, ssh, docker, etc.)
- Suggestions only shown for edit distance <= 2

https://claude.ai/code/session_012MkWqsq7cuwfd3RpsF5RCT
Closes #331

- Supports scale=N for decimal precision control
- Basic arithmetic: +, -, *, /, %, ^ with proper precedence
- Comparison operators: ==, !=, <, >, <=, >=
- Parenthesized expressions, unary minus
- Variable assignment and lookup
- Math functions: sqrt, s(in), c(os), a(tan), l(n), e(xp)
- -l flag enables math library with scale=20 default
- Stdin pipe support (echo "expr" | bc)
- Multiple expressions via newlines/semicolons
- 20 unit tests, 15 spec tests

… tests

Closes #334

- Fix process substitution path collision: replace timestamp-based naming
  with atomic counter (PROC_SUB_COUNTER) for unique /dev/fd/proc_sub_N paths
- Add spec tests for diff, paste, sort with process substitution
- Verify <(cmd) works for all agent-common patterns
- Process substitution already supported for <(cmd) input form

https://claude.ai/code/session_012MkWqsq7cuwfd3RpsF5RCT
Closes #333

- Add VfsSnapshot type with serde Serialize/Deserialize for VFS state
- Add InMemoryFs::snapshot() / InMemoryFs::restore() for full VFS capture
- Add ShellState type with serde for interpreter state (variables, env,
  cwd, arrays, aliases, traps, options)
- Add Bash::shell_state() / Bash::restore_shell_state() for shell state
- Combined usage enables checkpointing/rollback across agent turns
- 10 integration tests covering VFS, shell state, serialization, and
  combined multi-turn scenarios
- Update spec 009-tool-contract with snapshot/restore documentation

https://claude.ai/code/session_012MkWqsq7cuwfd3RpsF5RCT
Closes #329

- Add mypy step to Python CI lint job
- Add mypy config to pyproject.toml (python 3.9, ignore_missing_imports)
- Fix missing reset() method in _bashkit.pyi type stub
- All 5 Python source files pass mypy cleanly

https://claude.ai/code/session_012MkWqsq7cuwfd3RpsF5RCT
Closes #321

- Add max_loop_iterations and max_commands enforcement tests
- Add error condition tests: malformed syntax, nonexistent command,
  large output, empty input
- Add ScriptedTool edge cases: RuntimeError/TypeError callbacks,
  large output, empty return, async multi-tool
- 11 new test cases covering previously untested scenarios

https://claude.ai/code/session_012MkWqsq7cuwfd3RpsF5RCT
Closes #312

- Test langchain.py: import guard, create_bash_tool/create_scripted_tool
  ImportError when langchain not installed, __all__ exports
- Test deepagents.py: import guard, create_bash_middleware/
  create_bashkit_backend ImportError, __all__ exports, _now_iso helper
- Test pydantic_ai.py: import guard, create_bash_tool ImportError,
  __all__ exports
- All tests work without external framework dependencies

…on-level

Partial fix for #327

- Convert 5 builtin files from module-level #![allow(clippy::unwrap_used)]
  to function-level #[allow(clippy::unwrap_used)] with safety comments
- echo.rs: allow on interpret_escape_sequences (hex digit validated)
- path.rs: allow on Basename::execute (args checked non-empty)
- printf.rs: allow on 4 parse functions (peek before next pattern)
- sortuniq.rs: no allows needed (only unwrap_or/unwrap_or_default)
- fileops.rs: allow on Cp/Mv/Chmod execute (length/validity checked)
- Remaining 9 files (interpreter, parser, fs, large builtins) keep
  module-level allows due to pervasive validated unwrap patterns

Apply cargo fmt and ruff fixes across Rust and Python code.
