Fix Live accept for Elixir templates in lib/

[heliumbrain]

What broke

In Phoenix apps, Live often wraps markup that lives in lib/** inside a ~H""" block in a .ex file. Accept in the browser runs live-accept.mjs, which searches the tree for impeccable-variants-start markers.

That search only considered a handful of frontend extensions (.html, .jsx, …) and directories like src/ and app/. It never looked at .ex files or lib/, so accept returned Session markers not found even though the session was valid.

What changed

• live-accept.mjs and live-wrap.mjs now include .ex, .heex, .exs, and .eex, and search under lib/ as well.
• A small regression test accepts a variant from lib/my_app_web/components/layouts.ex.

How I checked

node --test tests/live-accept.test.mjs

All tests in that file pass (including the new case).

Note

Detector hooks recently gained configurable template extensions (#316 / #347). Live wrap/accept still uses its own hardcoded list; this PR only extends that list for a common Elixir layout. Happy to fold into a broader Live pass if #371 is the better home.

Note

Low Risk
Narrow search-path and file-extension changes to Live CLI helpers, covered by a new accept test; no auth or data-path changes.

Overview
Live accept/wrap no longer miss Phoenix-style markup in lib/** inside ~H""" blocks in .ex files. live-accept.mjs and live-wrap.mjs now scan .ex, .heex, .exs, and .eex and include lib/ in their project search paths (alongside src/, app/, etc.), so browser Accept can find impeccable-variants-start markers instead of returning Session markers not found.

A regression test accepts a variant from lib/my_app_web/components/layouts.ex. Live still uses its own hardcoded extension list (not the configurable detector hooks from other work).

Greptile Summary

This PR expands Live wrap and accept discovery for Phoenix-style Elixir templates. The main changes are:

• Adds .ex, .heex, .exs, and .eex to the Live file extension lists.
• Adds lib/ to the Live wrap and accept search directories.
• Adds a test for accepting a variant from lib/**/layouts.ex.

Confidence Score: 5/5

Safe to merge with minimal risk.

The changes are small and localized to hardcoded Live search extensions and directories. The added test covers the reported Phoenix lib/ accept path. No correctness or security issues were found in the changed code.

No files require special attention.
