v0.10.0 Feature and Maintenance Release

This release consolidates the unpublished 0.9.15 maintenance work and adds opt-in Gemini Notebook Enterprise support.

Added

Gemini Notebook Enterprise support (PR #309) — CLI and MCP users can target Enterprise notebooks on Cloud or Vertex hosts with project/location-aware routing, profile-based credentials, Enterprise notebook listing and queries, and Enterprise-aware notebook URLs. Enterprise mode is opt-in; personal Gemini Notebook routing remains the default when Enterprise settings are absent. Thanks to @Fang-Bo-Hsieh for the original implementation and live redacted Cloud Enterprise verification.
Dia browser authentication (PR #313) — Dia is supported as a macOS Chromium-family authentication browser. Thanks to @thezaidsheikh.

Studio artifact recovery and downloads (#315, #305) — Generic type-10 artifacts are classified by MIME, exposed consistently through CLI and MCP JSON, and downloadable with the correct filename extension. XLSX data tables preserve .xlsx by default while CSV data tables preserve .csv.
Query parser memory use (#314) — Query response parsing no longer creates full-body strip/split copies that could multiply memory use and trigger out-of-memory failures on source-heavy notebooks.
Authentication and media edge cases (#302, #304, #310, #311) — Browser discovery covers Chromium-family variants, rebranded Notebook hosts are recognized during CDP login, expired credentials are distinguished from network failures, and transient audio downloads retry the current media host.
Private vulnerability intake (#308) — GitHub private vulnerability reporting is enabled for safer security disclosures.

Added Enterprise setup, authentication isolation, project/location requirements, RPC provenance, URL examples, and a focused Enterprise test plan.
Enterprise live verification covers the Cloud host; the Vertex host has regression coverage but still needs an Enterprise deployment for independent live validation.

Full tracked-tree suite after the 0.10.0 version bump: 1,477 passed, 39 skipped.
Ruff lint and formatting, package build, and version-alignment checks passed on the merged Enterprise head.

Thank you to @Fang-Bo-Hsieh, @thezaidsheikh, @dankkush, @Rahulk644, @astrofoley, @winsonhung77, @bubandpop, @Naor-Peretz, and @zaidLMS for the contributions, detailed reproductions, measurements, real artifact checks, browser diagnostics, and security feedback that made these fixes easier to verify and ship.
