v0.25.0 — IDE OAuth + QA Documentation

[0.25.0] — 2026-06-23

Added

• Experimental IDE OAuth (off by default). A new /api/oauth/ide/* subsystem that lets AI coding agents (Claude Code, Codex CLI, Copilot, Cursor, Cline, Kilocode, Antigravity, xAI) authenticate via OAuth 2.0 PKCE or device flow — no manual API key management. Gated behind --oauth-ide-enable=false and admin-only dashboard controls.
• 8-provider OAuth IDE catalog (internal/oauthide/): Claude (PKCE), Codex (PKCE), GitHub Copilot (device flow), Cursor (device flow), Cline (PKCE), Kilocode (PKCE), Antigravity (PKCE), xAI (PKCE+device flow).
• 9-router port: the IDE OAuth layer reuses the 9router routing substrate, inheriting its multi-provider connection management infrastructure.
• Dashboard OAuth IDE page (/dashboard/oauth-ide): status card per IDE, self-service toggle, credentials display, connection health check.
• QA documentation: docs/qa-test-plan.md and docs/qa-test-report.md covering beta-readiness P0+P1 batch and OAuth IDE experimental feature.

Changed

• Repo renamed from lintasan-go → lintasan across all docs, badges, and remote URLs.
• README badges updated: version → v0.25.0, test count → 900+
• AGENTS.md reconciled to reflect the repo rename.

Tests

• 3 new test files for OAuth IDE
• Suite: 43/43 packages PASS, go vet clean, 900+ tests

Bug Fixes (from P1 audit)

• All rows.Scan() errors now checked (was silently swallowed — data corruption risk)
• Dead _ = lastStatusCode replaced with real status propagation to client
• Hardcoded stubs (requestVolume, tokensCompressed, prompt-routing) replaced with real data or honest 503s
• Rate limit config moved to Config struct, JWT secret error handling fixed
• 18 new bugfix tests, 106 total handler tests pass
