change in debug_heex_annotations should force recompilation

[ruslandoga]

👋

Environment

• Elixir version (elixir -v): 1.17.3
• Phoenix version (mix deps): 1.7.18
• Phoenix LiveView version (mix deps): 1.0.0
• Operating system: Darwin 24.1.0
• Browsers you attempted to reproduce this bug on (the more the merrier):
• Does the problem persist after removing "assets/node_modules" and trying again? Yes/no:

Actual behavior

Making this change in config/dev.exs

config :phoenix_live_view,
  # Include HEEx debug annotations as HTML comments in rendered markup
- debug_heex_annotations: true,
+ debug_heex_annotations: false,
  # Enable helpful, but potentially expensive runtime checks
  enable_expensive_runtime_checks: true

and running the app again with iex -S mix doesn't seem to recompile the templates and keeps showing the annotations in the templates rendered with Phoenix.View.render_to_string

Right now I'm using mix compile --force as a workaround.

Expected behavior

Maybe debug_heex_annotations could force recompilation of the templates.

The docs do say:
“Changing this configuration will require mix clean and a full recompile.”

I think it can be better -- automatic :)

Or at least we can include that note in the generated config files.
