[ci skip] Flatten module wrappers into stack roots

Remove the module "xxx" { source = "./module" } indirection layer
from all 66 service stacks. Resources are now defined directly in
each stack's main.tf instead of through a wrapper module.

- Merge module/main.tf contents into stack main.tf
- Apply variable replacements (var.tier -> local.tiers.X, renamed vars)
- Fix shared module paths (one fewer ../ at each level)
- Move extra files/dirs (factory/, chart_values, subdirs) to stack root
- Update state files to strip module.<name>. prefix
- Update CLAUDE.md to reflect flat structure

Verified: terragrunt plan shows 0 add, 0 destroy across all stacks.

+# Phase 1 Plan 1: Scraper Validation Summary
+
+**URL validation pipeline with 18 video/player markers filtering scraped links before store merge, configurable via SCRAPER_VALIDATE_TIMEOUT**
+
+## Performance
+
+- **Duration:** 3 min
+- **Started:** 2026-02-17T20:49:16Z
+- **Completed:** 2026-02-17T20:51:54Z
+- **Tasks:** 3
+- **Files modified:** 4
+
+## Accomplishments
+- Created validate.go with 18 video/player markers covering HTML5, HLS, DASH, and 10+ player libraries
+- Wired validateLinks into scrape() pipeline between URL extraction and store merge
+- Added SCRAPER_VALIDATE_TIMEOUT env var (default 10s) following existing config patterns
+- Added 25 unit tests (10 positive + 4 negative marker tests, 6 positive + 5 negative content type tests)
+
+## Task Commits
+
+Each task was committed atomically:
+
+1. **Task 1: Create validate.go with video marker detection** - `adeb478` (feat)
+2. **Task 2: Wire validation into scraper pipeline and add config** - `22d29db` (feat)
+3. **Task 3: Add unit tests for validation functions** - `6c5cc02` (test)
+
+## Files Created/Modified
+- `internal/scraper/validate.go` - URL validation with video marker detection (validateLinks, hasVideoContent, containsVideoMarkers, isDirectVideoContentType)
+- `internal/scraper/validate_test.go` - Table-driven unit tests for marker detection and content type checks (25 cases)
+- `internal/scraper/scraper.go` - Added validateTimeout field and validateLinks call in scrape()
+- `main.go` - Added SCRAPER_VALIDATE_TIMEOUT env var read (default 10s)
+
+## Decisions Made
+- Used string matching (not DOM parsing) for video detection -- DOM parsing reserved for Phase 4 link extraction
+- Set 2MB body read limit to prevent memory issues on large streaming pages
+- Limited redirects to 3 to avoid infinite redirect chains on sketchy stream sites
+- Validation runs sequentially (not concurrent) to avoid overwhelming target sites
+
+## Deviations from Plan
+
+None - plan executed exactly as written.
+
+## Issues Encountered
+None.
+
+## User Setup Required
+
+None - no external service configuration required.
+
+## Next Phase Readiness
+- Validation pipeline is integrated and tested, ready for health check layer (Phase 2)
+- The validateLinks function provides the filtering foundation that health checks will build upon
+- No blockers or concerns
+
+## Self-Check: PASSED
+
+All 5 files verified present. All 3 task commits verified in git log.
