feat: migrate-from-smush + Picture-tag rewriter (v0.2.0)

Browse Source 
Unblocks production use on sites previously running Smush.

migrate-from-smush:
  - Reads wp-smpro-smush-data postmeta, writes _h4b_img_optim marker
  - --dry-run / --force-rescan / --remove-smush-meta / --limit flags
  - Verified: 100 attachments migrated cleanly on dev.rds.ink,
    bulk count drops from 734 → 634

Picture_Tag rewriter:
  - Hooks the_content + post_thumbnail_html + widget_text + Elementor
    frontend + wp_get_attachment_image at priority 99
  - Wraps <img> in <picture><source avif><source webp><img></picture>
    when sibling files exist
  - Double-wrap protection via byte-range tracking of existing <picture> blocks
  - Per-image opt-out via data-no-h4b attribute
  - Cached sibling lookups per request
  - 8 edge-case tests pass

LOC: 2480 (was 1997). Adds class-cli-migrate.php (193 LOC) and
class-picture-tag.php (284 LOC).
