* feat: add cumulative resource score tracking across partial renders
Add cumulative_render_score and cumulative_assign_score counters to
ResourceLimits that accumulate across reset() calls, with optional
cumulative_render_score_limit and cumulative_assign_score_limit to
cap total work across all partial renders.
Also add a reached? check in BlockBody's render loop so that once a
cumulative limit triggers, the parent template stops processing
further nodes.
Bump version to 5.12.0.
* refactor: move cumulative limit enforcement into reset()
Instead of checking reached? in BlockBody's render loop, enforce
cumulative limits in reset() itself. Since reset() is called before
the begin/rescue MemoryError block in Template#render, the raise
propagates to the parent naturally — no changes to BlockBody needed.
- nil is NOT empty (but IS blank) - matches Shopify production
- String first/last returns '' for empty strings, not nil - matches ActiveSupport
- Add test for nil not being empty
Implement ActiveSupport-compatible behaviors internally so Liquid works
correctly without ActiveSupport being loaded:
1. String first/last via property access (name.first, name.last)
- VariableLookup now handles string[0] and string[-1] for first/last
2. String first/last via filters (name | first, name | last)
- StandardFilters#first and #last now handle strings
3. blank?/empty? comparisons for types without these methods
- Condition now implements liquid_blank? and liquid_empty? internally
- blank? matches ActiveSupport: nil, false, empty/whitespace strings,
empty arrays/hashes are all blank
- empty? checks length == 0 only (whitespace is NOT empty)
This fixes spec failures for templates like:
- {{ name.first }} / {{ name | first }} on strings
- {% if x == blank %} for whitespace strings, empty hashes/arrays
- {% case ' ' %}{% when blank %} matching whitespace
Previously, strict2 case/when used `safe_parse_expression`
to parse when expressions causing `blank`/`empty` to be
treated as string literals (Expression::LITERALS maps 'empty' => ''),
rather than method literals
This caused unexpected behavior:
```
{%- case empty_obj -%}
{%- when empty -%}
previously: doesn't render (empty_obj == '' is false)
now: renders (empty_obj.empty? is true)
{%- endcase -%}
```
This commit instead calls `Condition.parse_expression`
with `safe: true`, which will correctly handle `blank`
and `empty`
This commit reverts the Inline Snippets tag (#2001) and bumps
Liquid to 5.11. For now, the inclusion of Inline Snippets
in the latest Liquid release is being treated as a bug.
While #2001 does implement the scope contained in RFC#1916,
we need to take a step back to make sure we’re setting our
sights high enough with this feature, and that we’re truly
supporting theme developers in the ways they need.
If you have any feedback, please leave a comment on RFC#1916.

Most of changes update this:
```
[:lax, :strict].each do |mode|
with_error_mode(mode) do
assert_template_result(...
```
to be this:
```
with_error_mode(:lax, :strict) do
assert_template_result(...
```
* lax_parse - no changes
* strict_parse - uses the `lax_parse_filter_expressions` (as it was doing before)
* rigid_parse - uses the `rigid_parse_filter_expressions`
* Remove development helpers from parse context
* Simplify strict_parse_with_error_mode_fallback and update
documentation
* Add unit tests for `Liquid::Expression` and `Liquid::ParseContext`
* Update test helpers to work better with the `:rigid` mode
Previously the blank? method always returned true. Now it properly checks
if the body is empty, making the tag behavior consistent with other tags.
Also updated test to use whitespace control for cleaner assertions.
