chore(release): v0.26.0 DQS Workspace UI and Deterministic Quality Platform

[PythonWoods-Dev]

Summary

Prepares the v0.26.0 release of Zenzic Core, introducing programmatic CLI JSON output (--json flag) and realigning the public roadmap for the Deterministic Quality Platform.

Key Changes

• CLI Shorthand Alias (ECOSYSTEM-FEAT-002): Added --json flag to zenzic score as an ergonomic shorthand for --format json. Emits a single deterministic ScoreReport JSON object on stdout with no rich/text output, enabling non-blocking editor integration.
• Mirror Law CLI Documentation (ADR-020): Updated docs/reference/cli.md with complete flag documentation (--json, --breakdown, --save, --check-stamp, --no-header, --ci) and full JSON Output Schema specification.
• Roadmap Realignment (ROADMAP-ALIGN-004): Updated ROADMAP.md and internal priority matrix to establish [v0.26] as DQS Workspace UI, shifting subsequent platform milestones (v0.27–v0.30).

Quality Gates

• just verify: 1484/1484 passed (pytest, ruff, mypy, REUSE, pre-commit)
• zenzic check all --strict: DQS 98/100 (Gate Passed)
• just docs-build: mkdocs build --strict passed with zero errors

Invariants Preserved

• Radical Unawareness (ADR-075): Core emits JSON to stdout, completely unaware of downstream consumers (VS Code, CI/CD).
• Zero Subprocess: No child processes spawned by Core.
• Determinism: Mathematically identical scoring contract.
