Added Blazor Hybrid support to Bsqlite, using native SQLite and device-local file storage. Existing registration works across browser and Hybrid apps, with Hybrid storage selected automatically.
Added guidance for migrating existing Besql data and applications to Bsqlite, including support for opening legacy database files.
Changes
Retired Besql and removed its product pages and listings. Previous Besql URLs now redirect to Bsqlite.

Walkthrough
Bsqlite adds native SQLite and file-system storage for Blazor Hybrid, with host-aware provider selection and package support. The changes also add Hybrid tests and migration guidance, remove the Besql library and demos, update repository references, and redirect Besql routes to Bsqlite.

Summary
File-system provider and storage operations src/Utilities/Bsqlite/Bit.Bsqlite/Storage/*, src/Utilities/Bsqlite/Bit.Bsqlite/Interop/Storage/BsqliteFileStorageBindingStore.cs, src/Utilities/Bsqlite/Tests/Bit.Bsqlite.Tests/Storage/*
Bsqlite adds a file-system provider, configurable root directory, database administration operations, and file-based provider bindings.
Host-aware selection and native transport src/Utilities/Bsqlite/Bit.Bsqlite/BsqliteHost.cs, src/Utilities/Bsqlite/Bit.Bsqlite/Interop/*, src/Utilities/Bsqlite/Bit.Bsqlite/Interop/Transport/*, src/Utilities/Bsqlite/Bit.Bsqlite.Testing/*
Host detection and provider resolution support native-process execution. File-storage providers use BsqliteNativeTransport, which executes SQLite operations and reports committed table changes.
Package integration and Hybrid validation src/Utilities/Bsqlite/Bit.Bsqlite/Bit.Bsqlite.csproj, src/Utilities/Bsqlite/Bit.Bsqlite/buildTransitive/*, src/Utilities/Bsqlite/Tests/*
The package includes the native SQLite bundle and excludes its assets from applicable browser-WASM builds. Tests cover provider behavior, transport conformance, Hybrid persistence, provider selection, and existing database files.
Migration guidance and Bsqlite references README.md, src/Utilities/Bsqlite/README.md, src/Utilities/Bsqlite/docs/*, src/Utilities/Bsqlite/Demo/*
Documentation and demo guidance describe Hybrid support, its file-system backend, and migration from Besql.
Besql removal and repository updates .github/agents/*, .github/workflows/*, src/Besql/*, src/Bit*.slnx, src/Websites/Platform/src/*
The Besql library, demos, CI and publishing steps, and website pages are removed. Product references are updated, and legacy Besql routes redirect to Bsqlite.

The Hybrid backend is mostly sound, but a few edge cases should be fixed or acknowledged before release. Deleting a database in a missing folder can fail on Windows. Registering the file-system provider through a factory can break database opens. The first open may briefly block the UI thread. Some Hybrid docs and MCP descriptions are out of date.

Explanation
Issue #14197 has two coding requirements. (1) Merge Besql into Bsqlite and remove Besql from the repository. The PR deletes the src/Besql tree, including Bit.Besql, its demo projects, and Bit.Besql.slnx. It removes the Besql entries from src/Bit.slnx and src/Bit.CI.Release.slnx. It removes the Besql CI workflow and the Besql build and pack steps from all.ci.yml, nuget.org.yml, and prerelease.nuget.org.yml. Bsqlite gains the browser and Blazor Hybrid capabilities needed to replace Besql. (2) Replace Besql usages with Bsqlite. The PR updates the README, the Besql website pages (now redirected to Urls.Bsqlite), the CLAUDE.md edit boundary, the chatbot prompts, the Markdown demo text, the Mcp guides, and the Bsqlite docs. It adds a migrating-from-besql guide and a legacy Bit.Besql file import path with a test. The issue timing says 'in the next release'. The PR performs the replacement in this change. The summary does not provide a repository-wide search, so completeness of remaining references is not fully verified. No requirement depends on the ignored files.
Full details: Out of Scope Changes check
Explanation
Most changes map to the issue objectives. Removals under src/Besql, solution entries, CI workflows, and website Besql pages implement the removal. Reference updates in docs, demos, website, and tooling implement the usage replacement. New Bsqlite Blazor Hybrid code (BsqliteNativeTransport, BsqliteFileSystemStorageProvider, BsqliteHost, BsqliteNativeFunctions, the file-system binding store, and the transport factory) provides the non-browser path that Besql covered. Besql used a no-op storage and DbContext factory outside browsers. Its replacement is therefore required for the merge. The legacy file import, the migration guide, and the related tests (CacheStorageTests, BlazorHybridTests, file-system conformance tests, and McpOracleTests) support the migration. The Bsqlite.Testing changes support the new native transport. The BitAssembliesTests and minifier test change removes the deleted Besql directory from discovery. The Hybrid feature set is larger than the issue text describes. The connection to Besql migration is concrete, so no unrelated change is demonstrated.

Comment @coderabbitai help to get the list of available commands.
Describe the native backend separately from the memory backend.
When a caller requests file-system, this branch says its storage is “the engine’s own memory.” BsqliteFileSystemStorageProvider has no VFS module because native SQLite opens a persistent device file. Render a file-system-specific explanation instead; otherwise the provider reference gives the wrong persistence model.

Update the VFS description in the catalog rendering logic to distinguish the

Minor · Update the storage tool description for the fifth backend. · McpController.cs:138
Update the storage tool description for the fifth backend.
GetBsqliteStorageProviders now returns file-system, but its advertised description still says “four first-party storage backends” and “all four.” MCP clients receive that description before calling the tool. Include the Hybrid backend so clients do not exclude it when choosing a provider.

- Line 27: Update the Step 3 hosting-selection flow in McpPrompts so
`PlanBsqliteStorageSelection` is skipped for `hybrid` or uses a Hybrid-aware
plan; ensure Hybrid predicts the host-selected `file-system` backend rather than
a browser backend.
Review comments at @src/Utilities/Bsqlite/docs/migrating-from-besql.md:
- Line 37: Update the lifetime description in the migration table to say that
Blazor Hybrid uses one scope per web view, matching the documented scope
boundary. Keep the WebAssembly description unchanged.
