chore(release): v0.26.0 Core Baseline Alignment and Async DQS Status Bar

[PythonWoods-Dev]

Summary

Prepares the v0.26.0 release of the Zenzic VS Code Extension, realigning the pinned Zenzic Core baseline to 0.26.0 and implementing the Asynchronous DQS Status Bar CLI Execution Bridge.

Key Changes

• Async DQS Status Bar (ECOSYSTEM-FEAT-002): Restores the Document Quality Score (DQS) in the VS Code Status Bar ($(dashboard) Zenzic DQS: {score}/100) via an asynchronous child_process.execFile bridge running zenzic score --json.
• Zero LSP Performance Degradation: The LSP server (server.py) remains focused on sub-50ms incremental analysis. DQS execution is completely decoupled and triggered on-demand or via Status Bar click.
• Graceful Error Handling: Full resilience for ENOENT (binary missing), timeout (60s), non-zero exit codes (surfaces score even if failing threshold), and JSON parse errors.
• Core Baseline Pinning: Realigned minimum required Core version to 0.26.0 across package.json, src/extension.ts, README.md, and RELEASE.md.

Quality Gates

• just verify: ESLint (0 errors), TypeScript tsc --noEmit (0 errors), REUSE compliance (23/23 files compliant).

Invariants Preserved

• Determinism: Uses the exact same binary and CLI execution engine as CI/CD.
• Thin Client: Extension parses JSON output without duplicating scoring logic.
