hugocasaandClaude Opus 5 48f00259c5 feat: support $flow_expr[...] dynamic tags on flow steps (#11170)
* feat: resolve $flow_expr[...] dynamic tags on flow steps

Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

* fix: run an unresolvable $flow_expr tag on the default tag and give it the step input scope

Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

* refactor: resolve $flow_expr tags by path lookup instead of expression evaluation

Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

* docs: say a $flow_expr tag fails to resolve, not to evaluate

Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

* fix(frontend): word the $flow_expr help like the other dynamic tag lines

* fix: reject a malformed $flow_expr placeholder instead of queueing its literal tag

Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

* refactor: render $flow_expr tag values through the $args path lookup

Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

* test: pin interpolate_args through the shared tag path rendering
