v0.2.0

Added

• CLI resource limits for initial loading and reloading: --max-input-bytes (8 MiB), --max-nodes (100,000), and --max-depth (128). Set a limit to 0 to disable it for trusted input.
• bubbletea.WithAliasRowLimit to bound projected alias rows. The default is 10,000; nonpositive values hide projections without hiding ownership rows.
• Document accessors for sequence lengths, individual sequence items, mapping entries, and reverse reference lookups.
• Regression tests for YAML editing, snapshot isolation, terminal rendering, save conflicts, atomic saving, and Windows ACL preservation.
• YAML round-trip and selector fuzz tests, plus Linux and Windows CI builds, vet checks, Linux race detection, and reachable vulnerability checks.

Changed

• CLI saves now prepare, flush, and close a temporary file before replacing the destination. Existing symlinks are preserved, file mode bits are retained, and Windows replacement preserves the destination's ACL.
• Document snapshots share unchanged immutable nodes; builder mutations copy only affected nodes.
• Capability and selector resolution avoid copying entire parent containers. Deletion checks use reverse reference indexes instead of scanning the full document for every candidate.
• Terminal tree rows are cached across unchanged views and refreshed when the document, expansion state, or validation results change.
• Terminal widths, clipping, cursor movement, and deletion account for wide characters and grapheme clusters.
• Embedding documentation delegates saving to an application-owned persistence callback and describes resource limits and safe file replacement.

Fixed

• Optional YAML mapping entries can be deleted when schema and policy allow it, while mapping keys remain protected from editing.
• Moves that would place a YAML alias before its anchor are rejected without changing the document or history.
• NaN values produce validation errors when numeric minimum or maximum constraints are configured.
• Input-derived terminal control sequences and bidirectional formatting controls are displayed as escaped text without modifying stored values.
• Failed file writes or save preparation no longer truncate the original file.
