* feat: harness engineering P0 - linting, testing, architecture docs
Add foundational infrastructure for agent-first development:
- AGENTS.md: agent entry point with progressive disclosure to deeper docs
- ARCHITECTURE.md: 12-section system reference with source-file refs and ownership rule
- Biome 2.4.7 linter with project-tuned rules, CI workflow (lint-code.yml)
- Architectural boundary lint enforcing forward-only dependency direction (lint-boundaries.mjs)
- Unit test CI workflow (test.yml), all 1083 tests passing
- Fixed 9 pre-existing test failures (bootstrap sync, deploy-config headers, globe parity, redis mocks, geometry URL, import.meta.env null safety)
- Fixed 12 architectural boundary violations (types moved to proper layers)
- Added 3 missing cache tier entries in gateway.ts
- Synced cache-keys.ts with bootstrap.js
- Renamed docs/architecture.mdx to "Design Philosophy" with cross-references
- Deprecated legacy docs/Docs_To_Review/ARCHITECTURE.md
- Harness engineering roadmap tracking doc
* fix: address PR review feedback on harness-engineering-p0
- countries-geojson.test.mjs: skip gracefully when CDN unreachable
instead of failing CI on network issues
- country-geometry-overrides.test.mts: relax timing assertion
(250ms -> 2000ms) for constrained CI environments
- lint-boundaries.mjs: implement the documented api/ boundary check
(was documented but missing, causing false green)
* fix(lint): scan api/ .ts files in boundary check
The api/ boundary check only scanned .js/.mjs files, missing the 25
sebuf RPC .ts edge functions. Now scans .ts files with correct rules:
- Legacy .js: fully self-contained (no server/ or src/ imports)
- RPC .ts: may import server/ and src/generated/ (bundled at deploy),
but blocks imports from src/ application code
* fix(lint): detect import() type expressions in boundary lint
- Move AppContext back to app/app-context.ts (aggregate type that
references components/services/utils belongs at the top, not types/)
- Move HappyContentCategory and TechHQ to types/ (simple enums/interfaces)
- Boundary lint now catches import('@/layer') expressions, not just
from '@/layer' imports
- correlation-engine imports of AppContext marked boundary-ignore
(type-only imports of top-level aggregate)
- Fix relative-time {{count}} placeholders in all 12 locales (5m ago, not m ago)
- Localize CommunityWidget: replace 3 hardcoded English strings with t() calls
- Add Linux AppImage to tech/finance Tauri configs, CI matrix (ubuntu-22.04), packaging scripts, and download-node.sh
- Fix language code normalization: add supportedLngs/nonExplicitSupportedLngs to i18next, normalize getCurrentLanguage()
- Translate ~240 untranslated English strings across 11 locale files (ru/ar/zh now 100% translated)
- Add components.community section to all 12 locales
- All 12 locales at 1130-key parity, 0 placeholder mismatches
