refactor(logger): extend sanitize() type coverage and fix type safety issues

[Copilot]

The sanitize() function lacked proper handling for several JavaScript built-in types and had type safety issues that caused linting errors.

Changes

Type Safety

• Fixed WeakSet typing from object to Record<string, unknown> to eliminate eslint ban-types error
• Corrected regex pattern to use explicit case sensitivity [a-fA-F0-9] instead of case-insensitive flag
• Moved Date handling before circular reference tracking (Dates convert to strings, don't need tracking)

Extended Type Support

• Map: Sanitizes values and detects sensitive keys
• Set: Sanitizes contained values including v2 tokens
• RegExp: Converts to string representation
• Buffer: Returns <Buffer> placeholder
• TypedArray: Returns <TypedArray> placeholder for Uint8Array, Int32Array, etc.

Test Coverage

Added 12 test cases covering new types and edge cases (60 total tests passing).

Example

sanitize({
  config: new Map([['token', 'secret'], ['host', 'localhost']]),
  tags: new Set(['public', 'v2xaabbccdd112233445566778899aabbccddeeff']),
  pattern: /test/gi,
  data: new Uint8Array([1, 2, 3])
})

// Returns:
// {
//   config: Map { 'token' => '<REMOVED>', 'host' => 'localhost' },
//   tags: Set { 'public', '<REMOVED>' },
//   pattern: '/test/gi',
//   data: '<TypedArray>'
// }

Just as a heads up, I was blocked by some firewall rules while working on your feedback. Expand below for details.

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• download.cypress.io
  • Triggering command: /opt/hostedtoolcache/node/24.13.1/x64/bin/node /opt/hostedtoolcache/node/24.13.1/x64/bin/node index.js --exec install (dns block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)
