chore(deps): Bump js-yaml from 5.2.3 to 5.4.0 in /agent-governance-typescript

[dependabot]

Bumps js-yaml from 5.2.3 to 5.4.0.

Changelog

Sourced from js-yaml's changelog.

[5.4.0] - 2026-08-25

Added

• Added the scalarStyleRules dumper option to customize string formatting. See Scalar styling for details.

Changed

• [breaking] Flattened the low-level AST node style representation. Scalar and collection nodes now use SCALAR_STYLE and COLLECTION_STYLE values; explicit tags use the separate tagged property. Alias nodes now contain only kind and anchor. This only affects code that directly constructs or edits AST nodes.
• [breaking] The sortKeys option was rewritten using AST mutation to avoid side effects.
• Reworked scalar style selection. This can change formatting without changing loaded values; in particular, whitespace-only strings are now double-quoted.

Fixed

• Accept a byte order mark at the start of each document in a stream, #791.
• Produce valid flow mappings with quoteFlowKeys and flowSkipColonSpace, including alias and property-only keys, #786.
• Preserve empty scalar items when converting block sequences to flow style.
• Do not apply the 1024-character simple-key limit to flow mapping keys.
• Count Unicode code points, rather than UTF-16 code units, for the 1024-character simple-key limit.
• Add an explicit document-end marker after keep-chomped block scalars when needed to preserve trailing newlines.

[5.3.0] - 2026-08-14

This release focuses on reworking the documentation and making small architectural improvements before moving forward.

Added

• Added completely new documentation.
• Exported DUMP_SCHEMA, the default schema used by the dumper.
• Added YAMLException.throwAt() for throwing an error at a source position.

Changed

• Changed flat constant exports to grouped exports: EVENT_ID, SCALAR_STYLE, COLLECTION_STYLE, and CHOMPING_MODE, along with their value types. The old exports are still preserved, but deprecated.
• Made identify mandatory for custom tag definitions. Use identify: () => false for load-only tags.

Deprecated

• Deprecated flat constant exports. Use grouped ones instead.
