fix(release): repair functions.php + ARCHITECTURE.md truncations from prior commit

The prior commit (4a506e1c) was assembled from a sandbox bash mount that
returned a truncated view of two files. Net effect:
  - functions.php was cut at line 235, dropping the closing of
    peptide_starter_inline_dark_mode_script() and its add_action
    registration. wp_head dark-mode script was effectively removed.
  - ARCHITECTURE.md was cut mid-paragraph and lost its Version section.

Both files are now rebuilt from main + minimum-delta patches:
  - functions.php: +4 minimal additions (perf-asset-policy @see, version
    bump, require_once, add_action). Dark-mode script preserved.
  - ARCHITECTURE.md: +3 lines (perf-asset-policy in inc/ tree, version
    banner bumped). Version section preserved.
  - style.css, CHANGELOG.md, CONVENTIONS.md: also rebuilt from main +
    targeted patches as a safety measure (no functional change vs the
    prior commit, just guaranteed-untruncated).

Verified: every file ends with a trailing newline; functions.php contains
the dark-mode add_action; ARCHITECTURE.md contains the Version section.
