feat: add action-based sub-route routing for dialogs and card actions

[heyitsaamir]

Summary

• Add dot-separated sub-route routing for dialog.open.{dialogId}, dialog.submit.{action}, and card.action.{action}, matching the pattern used by file.consent.accept and message.submit.feedback
• Route selectors match against value.data.dialog_id (dialog open), value.data.action (dialog submit), and value.action.data.action (card action)
• Pairs with the existing OpenDialogData and SubmitData card utilities that set these reserved fields

Usage

// Before: single catch-all handler with manual dispatch
app.on('dialog.open', (ctx) => {
  const dialogId = ctx.activity.value.data?.dialog_id;
  if (dialogId === 'simple_form') { ... }
});

// After: targeted handler per identifier
app.on('dialog.open.simple_form', (ctx) => { ... });
app.on('dialog.submit.submit_form', (ctx) => { ... });
app.on('card.action.save_profile', (ctx) => { ... });

Test plan

• New router tests verify sub-route selection for all three invoke types
• Existing catch-all routes (dialog.open, dialog.submit, card.action) continue to work
• Tested cards and dialogs examples and things work as usual.

Pull request overview

Adds action-based sub-route routing for specific invoke activities so handlers can be registered as dialog.open.{dialogId}, dialog.submit.{action}, and card.action.{action}, consistent with existing sub-route patterns like file.consent.accept and message.submit.feedback.

Changes:

• Extends invoke route typings to include dialog.open.*, dialog.submit.*, and card.action.* route keys.
• Updates Router invoke matching to select sub-routes based on reserved payload fields (value.data.dialog_id, value.data.action, value.action.data.action).
• Adds router tests validating sub-route selection and continued catch-all behavior.
