build(deps): Bump pino-loki from 2.6.0 to 3.0.0

[dependabot]

Bumps pino-loki from 2.6.0 to 3.0.0.

Release notes

Sourced from pino-loki's releases.

v3.0.0

⚠️ Breaking Changes

Node.js 20+ Required Node.js 18 is no longer supported. The minimum required version is now Node.js 20.

Batching Options Restructured

The batching configuration has been consolidated into a single object:

// Before (v2.x)
pinoLoki({ host: '...', batching: true, interval: 5 })
// After (v3.x)
pinoLoki({ host: '...', batching: { interval: 5, maxBufferSize: 10_000 } })
// Or simply omit for defaults, or set batching: false to disable

Default Buffer Limit

A new maxBufferSize option (default: 10,000) prevents out-of-memory issues when Loki is unavailable. When the buffer is full, oldest logs are dropped (FIFO).

Structured Metadata Enabled by Default

structuredMetaKey now defaults to 'meta'. Logs with a meta property will automatically send it as Loki structured metadata. Use structuredMetaKey: false to disable.

CLI Changes

• --batch => --batching
• --interval => --batching-interval
• --timeout default: 2000ms → 30000ms
• Added --batching-max-buffer-size
