chore(deps): bump yaml from 2.8.4 to 2.9.0

[dependabot]

Bumps yaml from 2.8.4 to 2.9.0.

Release notes

Sourced from yaml's releases.

v2.9.0

The changes here are really only patches, but I'm releasing this as a minor version to note a small change to the documentation of parseDocument() and parseAllDocuments(): I've removed the claim that they'll "never throw".

It remains the case that practically all non-malicious inputs will be handled without emitting an error, but there is a decent chance that code paths remain where e.g. a RangeError due to call stack exhaustion can be triggered by malicious inputs. Up to now, I've considered these as security vulnerabilities, and in fact it's the only category of error for which yaml CVEs have been issued so far.

Starting from this release, I'll be considering such errors as bugs, but not vulnerabilities. I do welcome people and/or LLMs looking for them, but please report them as normal issues rather than suspected security vulnerabilities. This also applies to previously undiscovered bugs in earlier releases.

• fix: Avoid calling Array.prototype.push.apply() with large source array
• fix(lexer): Avoid recursive calls that may exhaust the call stack

Note

Low Risk
Dependency-only bump with no code changes; 2.9.0 is a minor release with parser robustness fixes that should be compatible with existing parse() usage in frontmatter handling.

Overview
Bumps the yaml npm dependency from 2.8.4 to 2.9.0 in packages/coding-agent/package.json and the root lockfile. No application source changes.

2.9.0 includes lexer/parser hardening (avoids stack exhaustion and large-array push.apply issues) and clarifies that parse() / parseAllDocuments() are not guaranteed to never throw on hostile input. The agent still uses yaml mainly for frontmatter parsing in frontmatter.ts.

Note

Bump yaml dependency from 2.8.4 to 2.9.0 in coding-agent

Updates the yaml package version constraint in package.json from ^2.8.2 to ^2.9.0 and regenerates the lockfile accordingly.
