Add try_parse_tag_token that parses {%...%} tag tokens using
getbyte/byteslice + ByteTables lookup arrays instead of the
FullToken regex with 4 capture groups. Allocates only the 2
strings needed (tag_name, markup) vs 4+ from regex captures.
Uses ByteTables::WORD (no hyphen) for tag name scanning,
matching TagName = /#|\w+/ exactly. Falls back to FullToken
regex when the fast path returns nil.
Skip the expensive recursive VariableParser regex for simple
lookups like 'product.title' (~90% of real-world cases).
SIMPLE_LOOKUP_RE validates the input is a plain a.b.c chain
(no brackets, no quotes). On match, byte-walks on dots to split
segments instead of invoking the regex engine. Falls through to
the original VariableParser scan for complex inputs.
parse_number: replace INTEGER_REGEX/FLOAT_REGEX matching and
StringScanner loop with a single byte-walking pass using
ByteTables::DIGIT. Avoids MatchData allocation and StringScanner
reset on every call.
Expression.parse: only call String#strip when leading/trailing
whitespace is actually present (checked via ByteTables::WHITESPACE).
Avoids allocating a new String on ~4,464 calls per compile.
ByteTables provides pre-computed 256-entry boolean lookup arrays for
byte classification (IDENT_START, IDENT_CONT, WORD, DIGIT, WHITESPACE)
and named constants for delimiter bytes (NEWLINE, DASH, DOT, HASH).
bench_quick.rb measures parse µs, render µs, and object allocations
for the theme benchmark suite.
The pinned version (v1.273.0) does not have prebuilt `ruby-head` binaries
for `ubuntu-24.04`, which `ubuntu-latest` now resolves to. This causes CI
to fail with "Unavailable version head for ruby on ubuntu-24.04".
Updating to v1.295.0 picks up ubuntu-24.04 support for all Ruby versions
including head builds.

* 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.
liquid-spec main changed the adapter API:
- compile block now receives (ctx, source, options) and should store
the template in ctx[:template]
- render block now receives (ctx, assigns, options) and retrieves
the template from ctx[:template]

- Implement liquid_blank? and liquid_empty? methods in Condition
to emulate ActiveSupport's behavior when it's not loaded
- This ensures templates like `{% if x == blank %}` work identically
whether ActiveSupport is loaded or not
- Update liquid-spec adapters for new API (ctx parameter)
- Add rake spec task for running liquid-spec matrix

- 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
- Add liquid-spec gem from GitHub to :spec group
- Create spec/ruby-liquid.rb adapter for the reference implementation
- Add spec job to CI workflow to run liquid-spec tests
