will.anderson a3732a1e9a fix(parser): add {#if}/{#else}/{/if} support and raw-text <style>/<script> in HTML templates
El SDK CI - dev / build-and-test (pull_request) Failing after 18m3s
Details 
The El lexer silently skips '#', so {#each} lexes as LBrace Ident:"each"
and {#if} lexes as LBrace If ... (using the If keyword token, not Hash).
The existing {#each} check used k2=="Hash" which was dead code.

Parser changes (parser.el):
- Add parse_raw_text_content(): collects all tokens as raw text until
  </tag_name>, bypassing El expression parsing. Used for <style> and
  <script> elements so CSS/JS content isn't parsed as El expressions.
- parse_html_element(): use raw-text mode for <style> and <script> tags.
- parse_html_children(): fix {#each} detection (k2=="Ident", k3=="each"
  instead of dead k2=="Hash" check). Add {#if cond}...{#else}...{/if}
  support generating HtmlIf AST nodes.

Codegen changes (codegen.el):
- Add cg_html_if(): generates if (cond_c) { then_c } else { else_c }
  for HtmlIf nodes.
- cg_html_parts(): dispatch HtmlIf to cg_html_if.
