v0.11.0 — OpenRouter model picker (#111)

v0.11.0 — OpenRouter model picker (AJAX refresh + cost preview + Phase-2 asset extract)

Replaces the free-text slug inputs for analysis_model, writing_model, and editor_model with a smart picker fed by a daily-refreshed OpenRouter model registry. Picker shows context size + input/output price + provider, filters by per-field capability, previews per-generation cost using existing cost-tracker history, and keeps a custom-slug fallback. Daily registry refresh fires from inside on_daily_generation() before lock acquire — no new top-level cron event.

Commit sequence (preserved for review):
- 353aa4e  feat(models): OpenRouter model picker + AJAX refresh + cost preview
- 283fa55  fix(phpcs): resolve 4 PHPCS violations in model-registry-refresh handler
- 1b1336a  style(phpcs): fix array syntax in model field + cost tracker
- 283f9f9  style(phpcs): fix tabs vs spaces in settings-page.php
- aa78591  refactor(assets): extract model-picker refresh handler to generic-handle file

Verification
- PHPCS strict (CI scope): 0 errors / 0 warnings
- PHPUnit: 206/206 (555 assertions, 2 pre-existing skips)
- All new files under 300-line cap (field renderer 163, AJAX handler 82)
- Security: AJAX nonce + manage_options cap; output escaped; input sanitized
- Phase 2 ready: zero PRAUTOBLOGGER_* coupling in registry/picker/AJAX classes; generic asset handle peptiderepo-model-picker

QA verdict: PASS (qa-reviews/prautoblogger/2026-04-23-aa78591.md)

Out of scope (untouched): cto-review.yml, prautoblogger_image_model field (Workers AI FLUX, Phase 3), Peptide Search AI / Peptide News fields (Phase 2).
