Add language support/mapping for .inc, .tpl, and .scss files

[Cyantix]

Description

When testing CortexKit AFT on our codebase, many relevant files were skipped as unsupported_language.

In our codebase, these extensions are important:

.inc should be treated as PHP
.tpl should be treated as Smarty templates
.scss should be treated as SCSS

Currently, AFT works well for .js and some .php files, but a large part of the actual application code is ignored because these extensions are unsupported. This makes tools like aft_outline, aft_zoom, and aft_inspect much less useful for PHP/Smarty/SCSS-heavy projects.

A first improvement could be simple extension mapping support, especially:

.inc => php
.tpl => smarty
.scss => scss

Even lightweight outline support for Smarty and SCSS would already be very helpful.

v0.35.0 ships two of the three. .inc is now parsed as PHP, and .scss is a recognized language. Both work with aft_outline, aft_zoom, and AST search.

.tpl (Smarty) is not included yet. There is no tree-sitter grammar for Smarty we can depend on, so we held it rather than ship something that parses unreliably. Leaving this issue open to track Smarty support.

Thank you so much, this is already a huge improvement for our 20+ years in development enterprise monorep :)
