- Switched template CSS/JS inlining replacements to callback form in generation scripts to avoid `$` replacement expansion semantics.
- Updated HTML export generation to use callback-based replacements for theme variables and session data injection to prevent accidental `$` substitution parsing.
- Added regression tests for the inlined script ensuring literal `$'` regex tokens remain intact, no closing HTML tags are injected, and the script parses via `new Function`.
The HTML export feed, sidebar tree, and TUI session tree did not handle
the developer role, so plan content injected after /plan approval (and
any other developer messages) was hidden from /export and shown as a
bare [developer] label in /tree.
Renders developer messages in the main feed with a dimmed
.developer-message style, labels them in the sidebar tree, counts them
in header stats, and shows their content in the TUI tree selector so
search matches the body.
Closes#753.
