Add dynamic-array unique() and unique_index() support and extend queue/darray min() and max() to accept locator with(...) predicates. Generate dedicated _with sfuns for min/max, emit VVP code for filtered scans, and reduce through new object-stack min/max opcodes.
Cover the new behavior with ivtest regressions for darray unique and queue/darray min/max with predicates, and update locator method documentation.

Implement queue and dynamic-array min()/max() for integral vec4 element types, with VVP support for both queue-backed and darray-backed storage and regressions in ivtest. Keep min/max as no-arg methods and document current behavior alongside existing locator tests.

Implement array locator methods for SystemVerilog queues and dynamic arrays:
find, find_index, find_first, find_first_index, find_last, find_last_index,
unique, and unique_index. Support both value arguments (equality) and
with (predicate) forms using implicit item and index in the iterator scope.
Elaboration returns queue-typed results for first/last/index locators per LRM
(empty queue when no match). Fix assignment compatibility between queues and
dynamic arrays where element types match.
VVP: extend %queue/size, %queue/word, %queue/find*, and %queue/unique* paths
so nets holding vvp_darray (including atom-backed int[]) are handled, not
only vvp_queue_vec4. Queue types still subclass vvp_darray; resolve vec4
queues before plain dynamic arrays. Fall back to the legacy get_queue_object
path for non-vec4 queues. Document opcode and source file touchpoints in
ivtest/ivltests/README_sv_queue_locators.txt.
Add vvp regressions: sv_queue_find*, sv_queue_unique, sv_queue_find_locators_ext,
sv_darray_find_locators.

Implement call_chain_expr in the parser, PECallFunction chain prefixes,
elaboration for class methods on returned handles, and prefix class resolution
for width checks on multi-hop chains. Place call_chain_expr before bare
hierarchy_identifier in expr_primary so id ( is not reduced as a lone ident.
Document behavior and developer notes in devel/sv_call_chain.md (including
that iverilog uses the installed lib/ivl/ivl binary).
Add ivtest sv_call_chain_method1 normal test with -g2012.
Made-with: Cursor
Add vvp regression for push_front, push_back, pop_front, pop_back on
queue-typed class fields. Catches vvp opcode_table sort regressions that
surface as Invalid opcode at runtime.

Internally, the maximum address space of a vector is 31 bits + a sign bit
to signal invalid addresses (out of bounds or has one or more x or z bits).
This commit ensures that unsigned part-select bit addresses which would
otherwise overflow and wrap around within this address space are correctly
handled as out of bounds.
Add a regression test to check that the right-hand side of a shift
operation is always treated as unsigned, even if it is a signed registers
or a variation thereof.

Check that assignments with undefined intra-assignment delay get executed
with zero delay. The assignment should not be skipped.
