v0.9.14 Feature and Maintenance Release

This release adds native collection management, improves long-running query behavior, and expands Windows browser authentication support.

Added

Native NotebookLM collections (#303) — The CLI and MCP server can create, list, edit, delete, and set emojis on native NotebookLM collections. Thanks to @rodrigopazTech for the contribution.
Windows standalone Chromium authentication (#302) — Standalone Chromium is discovered in standard machine-wide and per-user Windows installation locations and can be selected with nlm config set auth.browser chromium. Thanks to @zaidLMS for the request.

Source-heavy query timeouts (#298) — The configured timeout now governs the complete query operation, including preparatory notebook and conversation lookups. Timeout failures are mapped to structured, retryable errors on both synchronous and asynchronous paths. The default is 120 seconds; source-heavy notebooks may need a larger value such as 180 seconds. Thanks to @doc-parihar for the detailed reproduction and diagnostics.

Documented the query timeout budget, retry guidance, async polling workflow, and Windows Chromium discovery paths.

Full test suite, Ruff lint, formatting, package build, and version-alignment checks passed.
