Rename projects to Nimblesite.* namespace, remove Gatekeeper and Samples

[MelbourneDeveloper]

TLDR

Rename all project directories/assemblies to use Nimblesite.* namespace prefix, remove Gatekeeper and Samples (now in separate repos), restructure CI with per-project coverage enforcement, and add comprehensive test coverage.

What Was Added?

• coverage-thresholds.json — per-project coverage thresholds (88–92% depending on component)
• GlobalUsings.cs files added to projects that previously lacked them
• docs/specs/ directory consolidating all specification documents
• New test files with extensive coverage:
  • CoreCoverageTests.cs (912 lines) — DataProvider core coverage tests
  • GeneratedOperationsCoverageTests.cs (636 lines) — generated operations coverage
  • CodeGenerationExtendedE2ETests.cs (542 lines) — extended code generation E2E tests
  • FunctionMappingE2ETests.cs (293 lines) — LQL function mapping E2E tests
  • LqlDialectE2ETests.cs (462 lines) — LQL dialect E2E tests

What Was Changed or Deleted?

• Project renames (841 files across the repo): all projects renamed from short names to Nimblesite.* prefix (e.g. DataProvider → Nimblesite.DataProvider.Core, Lql → Nimblesite.Lql.Core, Sync → Nimblesite.Sync.Core, etc.)
• Deleted Gatekeeper — entire Gatekeeper/ directory removed (WebAuthn + RBAC auth module)
• Deleted Samples — all healthcare samples removed (moved to separate HealthcareSamples repo)
• Deleted skills — container-logs and run-samples skills removed (referenced deleted Samples)
• CI workflow restructured — from conditional path-filtered jobs to 3 parallel tracks:
  1. Lint + DataProvider Tests — format check, lint, DataProvider tests with coverage enforcement
  2. Build + LQL / Migration / Sync Tests — full .NET + Rust build, all component tests with per-project coverage thresholds
  3. LQL Extension Tests — TypeScript compile, VS Code extension tests, VSIX packaging
• CI coverage enforcement — each test project now checked against thresholds in coverage-thresholds.json
• .NET version set to 9.0.x in CI (was 10.0.x)
• Removed push-on-main CI trigger — CI now runs only on PRs and manual dispatch
• Solution file updated — all project references updated to new paths, removed Gatekeeper/Samples projects
• Spec docs moved — from component directories to docs/specs/
• TypeScript lint fix — explicit null/undefined check in index.ts to satisfy strict-boolean-expressions

How Do The Automated Tests Prove It Works?

All 1,977 tests pass across every component:

• DataProvider (462 tests): Nimblesite.DataProvider.Tests (277) + Nimblesite.DataProvider.Example.Tests (185) — source generation, SQLite integration, code generation E2E, core coverage
• LQL .NET (134 tests): Nimblesite.Lql.Tests — transpiler, dialect E2E, function mapping E2E
• LQL F# Type Provider (32 tests): Nimblesite.Lql.TypeProvider.FSharp.Tests
• LQL Rust (485 tests): lql-analyzer (228) + lql-lsp (131) + lsp_protocol (31) + lql-parser (95) — completions, diagnostics, hover, schema, scope, symbols, LSP protocol
• Migration (283 tests): Nimblesite.DataProvider.Migration.Tests — schema migration framework
• Sync (581 tests): Core (246) + SQLite (200) + Postgres (54) + Integration (14) + HTTP (67)
• LQL Extension: TypeScript compiles, VSIX packages successfully

Spec / Doc Changes

• All spec documents moved from component directories to docs/specs/ (gatekeeper, sync, migration, lql, website, design systems)
• CLAUDE.md updated to reflect architecture changes
• Website docs updated to remove Samples references

Breaking Changes

• All assembly/namespace names changed from short names to Nimblesite.* prefix
• Gatekeeper removed entirely — consumers must use the separate repo or remove auth dependencies
• All Samples removed — now live in MelbourneDeveloper/HealthcareSamples
• CI trigger changed — no longer runs on push to main, only on PRs and manual dispatch
