style: apply ruff format to source and test files - #45
Conversation
Formats 8 files per ruff's line-length=120 configuration: - src/configdrift/cli.py, diff.py, loader.py - tests/test_ci_workflow.py, test_cli.py, test_coverage_gaps.py, test_diff.py, test_loader.py Net reduction of 83 lines by consolidating multi-line expressions that fit within the 120-char limit. All 143 tests pass.

Implements the missing command referenced in the project description
('detects and fixes configuration file drift'). Given a baseline and target
config file, overwrites drifted keys in the target with baseline values.
- Supports JSON, YAML, TOML (with optional tomli-w), and flat-key write-back
- Preserves target-only keys (does not delete them)
- Adds missing baseline keys to target
- --dry-run/-n flag to preview without modifying files
- 8 new tests covering JSON/YAML/TOML round-trips, dry-run, edge cases
- All 155 existing tests continue to pass

Preserve nested JSON structure during fix
When a target JSON file contains nested objects, load_file() first flattens them into dotted keys, and this line serializes that flattened dictionary directly. For example, fixing {"database":{"host":"prod"}} produces {"database.host":"dev"}, changing the configuration schema rather than only its value; reconstruct the nested structure as the YAML/TOML branches do, or edit the raw parsed document.

When the target is a supported .env file, it loads successfully but always reaches this unsupported-format branch and exits without applying any changes. This leaves one of the tool's explicitly supported configuration formats impossible to fix; add .env serialization or reject it before presenting the command as format-agnostic.

Process every supplied target file
When users supply three or more paths, the list argument and “2+ files” validation accept them, but selecting only files[1] silently ignores every later target and still reports success. Iterate over files[1:] so all supplied environments are fixed, or reject extra paths explicitly.

Skip write-back when there are no changes
When baseline and target values already agree, changes remains zero but every non-dry-run invocation still enters the serializer. This needlessly rewrites the target and can remove YAML/TOML comments, formatting, and quoting despite there being nothing to fix; return successfully before write-back when changes == 0.

…tion on crash) Add _atomic.py module with tempfile+fsync+os.replace pattern for safe writes. Replace all direct file writes in the fix command (JSON/YAML/TOML) with atomic helpers that serialize to buffer first, then write to temp file and atomically rename. Original config files are now preserved intact if the process crashes mid-write (disk full, SIGTERM, power loss). 7 new tests verify the atomic-write contract including failure-mode preservation.

Preserve target permissions during atomic replacement
When an existing config is group- or world-readable, mkstemp() creates the replacement with mode 0600, and os.replace() installs that mode instead of preserving the target's metadata; ownership is likewise changed to the CLI user. After a successful fix, an application running under another account can therefore lose access to its configuration. Copy the existing file's mode/ownership to the temporary file before replacing it; the byte-writing helper has the same issue.

Replace scalar parents before rebuilding nested data
When the YAML baseline contains a mapping such as service: {host: dev} but the target contains the scalar service: disabled, merging produces both flattened keys service and service.host. Because the scalar is processed first, setdefault() returns the string and the following assignment raises TypeError, so fix cannot repair this ordinary scalar-to-mapping drift; TOML repeats the same reconstruction logic. Resolve parent/child conflicts while rebuilding or update the raw parsed tree instead.
