DeepSeek models on OpenRouter omit the usage object, causing all token
counts and costs to log as zero. Added character-based estimation
fallback (~3.75 chars/token), token_source column to distinguish
measured vs estimated data, and admin UI indicators (amber warnings,
~ prefix on estimates). Updated DeepSeek/Qwen pricing table.

is_budget_exceeded() used `0 === $budget` but floatval() returns float,
so 0 (int) === 0.0 (float) is always false. This caused unlimited
budget ($0) to be treated as exceeded, blocking all AI generation.
Same bug existed in the admin display (showed "$0.00" instead of
"Unlimited" for budget remaining).
This was a P1 bug that prevented ALL AI content generation since v4.3.0.

Replace the WP-Cron-based re-enrichment with an AJAX polling approach
that processes one peptide per request. This bypasses WP-Cron entirely,
which is unreliable on Hostinger shared hosting with LiteSpeed + Cloudflare.
New files:
- includes/class-psa-batch-enrichment.php — AJAX endpoints for status + process
- assets/js/psa-batch-enrich.js — Admin progress bar UI with polling loop
The admin settings page now shows a "Re-enrich Peptides" button with live
progress bar, per-item log, and automatic retry on failure. Respects the
daily generation cap and monthly budget.

Adds [peptide_directory] shortcode with card grid, category taxonomy (8 terms),
search, pagination, detail modal, and /v1/compounds REST endpoint. Includes 9
new meta fields (half-life, stability, solubility, etc.), admin data tools for
migration/re-enrichment, integration hooks for cross-plugin extensibility,
dark mode support, and full uninstall cleanup. Refactors AI generator into
PSA_OpenRouter + PSA_KB_Builder classes. Adds PHPUnit tests for PostType and
Directory classes. Fixes QA findings: dead JS selector, renderError loading
state, numeric meta validation, prepared SQL in uninstall.
