fix(deps): three advisories in the runtime dependency tree, two of them high - #81

…em high `npm audit --audit-level=high --omit=dev` is a required check and went red on main. The findings are real, all transitive, and all fixable inside the ranges package.json already declares — so this is a lockfile-only change. * fast-uri 3.1.4 -> 3.1.5 (HIGH, GHSA-7p8r-x3mc-p8w7). Host confusion via a backslash authority introducer: a URL whose authority is introduced with a backslash parses to a different host than a resolver reaches. Arrives through @anthropic-ai/claude-agent-sdk -> @modelcontextprotocol/sdk -> ajv. * ip-address 10.2.0 -> 10.4.0 (HIGH, three advisories). Address4 decoded leading-zero octets as decimal where resolvers read them as octal; a CIDR suffix suppressed special-use classification; IPv4-mapped and NAT64 IPv6 addresses were misclassified. Each one lets an address pass an SSRF or trust-boundary check and resolve somewhere else. * hono 4.12.31 -> 4.13.0 (moderate, GHSA-8j4g-w8fx-2239). ReDoS in the CORS middleware via Access-Control-Request-Headers. The advisory line matters for fast-uri: the fix for the 4.x line is 4.1.2 and for the 3.x line it is 3.1.5. This tree is on 3.x, so 4.1.2 is not the fix here. package.json is untouched — every bump is within an existing range, so nothing about what this package declares has changed. The audit reports zero vulnerabilities afterwards, and the 502 tests and lint pass on the new tree.

fast-uri's 4.x line is 4.1.2; for the 3.x line it is 3.1.5. This tree is on 3.x, so 4.1.2 is not the fix here — worth stating because the scanner output for a sibling repo names 4.1.2 and they are not interchangeable.package.jsonis untouched — every bump is within an existing range, so nothing about what this package declares has changed.Verified:
npm audit --audit-level=high --omit=devreports 0 vulnerabilities (exit code read from the command itself, not off the end of a pipe), 502 tests pass across 33 files, and lint is clean on the reinstalled tree.
