feat: ship batch idea export workflow, CLI-first deploy ops, and Chinese light-theme web experience

[weijt606]

PR Description

Overview

This PR merges the last 17 commits and delivers a full product + release-readiness upgrade across API, Web, CLI, CI, and docs.

The scope includes:

• Batch idea assessment/export capabilities (API + UI)
• Chinese web entry and upgraded light visual design
• CLI-first deployment workflow with Docker fallback
• Release preflight/post-deploy automation
• Observability and monitoring baseline
• CI/script reliability fixes for non-venv environments

What’s Included

1) Idea Assessment: Batch + Export

• Added batch assessment APIs with verdict aggregation.
• Added batch controls:
  • max_concurrency
  • per_item_timeout_seconds
• Added export endpoints for idea assessment reports:
  • Markdown
  • JSON envelope
• Added tests for:
  • batch assessment
  • batch export markdown/json
• Added README examples for the new endpoints.

2) Web UX for Idea Workflow

• Added batch assessment UI controls and summary rendering.
• Added batch report export actions in the UI.
• Added export history panel with:
  • recent records
  • clear history
  • persisted local history
• Added one-click re-export from history.
• Added snapshot-based re-export (replay original payload).
• Improved local-dev routing/ports for smoother parallel local projects.

3) Chinese Web Experience + Visual Refresh

• Added Chinese route entry and mapped zh pages for major flows.
• Added locale-aware navigation (EN/中文 toggle).
• Added locale-preserving project links.
• Upgraded to a premium, light-first visual style:
  • refined typography
  • warmer color system
  • elevated cards/hero treatments
• Updated README and README.zh-CN with main stack icon badges under the title area.

4) CLI-First Deploy & Ops (Docker as Backup)

• Added owlscope ops command group for operational workflows.
• Added commands:
  • owlscope ops preflight
  • owlscope ops check
  • owlscope ops deploy
  • owlscope ops stop
• Deploy behavior:
  • local-first direct mode
  • optional web startup/checks
  • Docker fallback path
• Lifecycle support:
  • detached/no-detached modes
  • managed runtime state file
  • stop/reap managed processes safely

5) Release & Deployment Automation

• Added release preflight workflow and scripts.
• Added production compose override profile.
• Added post-deploy verification script.
• Added web check script.
• Added env validation script.
• Added rate-limit check script.
• Added integration compare helper script.
• Added deployment runbook, migration/rollback guide, smoke checklist, and release template.

6) Observability Baseline

• Added lightweight telemetry counters.
• Added admin monitor endpoint for runtime status.
• Wired access logging to telemetry recording.
• Added API test coverage for monitor endpoint.

7) CI Reliability Fix

• Fixed release-check script to avoid hard dependency on local .venv.
• Applied same non-venv-safe behavior to integration helper script.
• This unblocks CI environments that install dependencies into system/python runner envs.

Validation

• API targeted tests passed for idea assess/export/batch flows.
• Integration compare black-box test passed after stabilization.
• Frontend production builds passed after each UI phase (including zh routes).
• Release preflight script completed successfully end-to-end.
• Post-deploy checks script completed successfully.
• CLI command discovery and operational paths validated, including lifecycle stop behavior.

Breaking Changes

• None intended.

Operational Notes

• Default local ports are aligned for multi-project coexistence:
  • API: 8010
  • Web: 3100
• Docker remains the fallback deployment path; local-first CLI is now primary for fast iteration.

Risk / Follow-up

• Non-blocking local machine warning remains around Next.js SWC native binary loading in some environments; builds still complete successfully.
• Future enhancement opportunity: add ops status to expose managed process health/log pointers in one command.
