GOKe v2.0.2 — fix exponential memory blowup in Query.Build

GOKe v2.0.1 — bounds-check fix in addr.Index

Index.Get/Upsert/Clear had a type mismatch in their bounds guards that
defeated bounds-check elimination on the hottest entity-lookup path.
Fixed by matching guard types to the access. No API/behavior changes.

GOKe v2.0.0 — rewritten public API, internal engine rebuild

Module path changed to github.com/kjkrol/goke/v2 (required by Go modules
for any v2+ release) — update your import accordingly.

Breaking changes vs v1.3.4:
- Free functions (goke.Tick(ecs, d), goke.RegisterSystem(...)) replaced
  by methods on *ECS
- View0-View10 / Blueprint1-Blueprint10 (generated, per-arity) replaced
  by Query/Factory/Editor built on component handles (Comp[T])
- GetComponent/SafeGetComponent/EnsureComponent removed — use
  Query.Seek + Comp[T].At
- System.Update(Lookup, *Schedule, Duration) -> Update(*CmdBuf, Duration)
- Internal package decomposition (arch/ent/comp/colstore/chunk/addr/reg/
  orch/query) replaces internal/core

Highlights:
- Pull-based iteration (Query.All/Pick + Next()+Cursor) replaces the
  push-based iter.Seq API, avoiding its inlining cliff on heavy loop
  bodies
- Zero allocations at steady state on Editor.Add/Del/Mix (chunk reuse)
- Unit test coverage raised to 96-100% across all packages

perf(core): inline Page values in Memo, contiguous multi-page allocation

- Memo.Pages changed from []*Page to []Page — eliminates per-page heap
  allocation and improves cache locality during page iteration.
- New Memo.AddPages(n) allocates n pages from a single contiguous memory
  block, reducing allocation count for batch entity creation.
- Blueprint.Create inlines page management logic and pre-allocates all
  required pages upfront via AddPages before filling them sequentially.
- View.All and View.Filter iterate pages by pointer (&Pages[i]) to avoid
  40-byte struct copies on each iteration.
- Removed Memo.AllocBatch (logic inlined into generated Blueprint code).

v1.3.1 — Adaptive Page Layout

Per-archetype PageBytes = PageCap × stride; wide structs no longer
panic (1 entity/page fallback).

- Removed RegistryConfig.DefaultArchetypePageSize (dead code).
- Fixed Reset() iterating over uninitialised Archetypes[0] slot.

v1.3.0 - iter.Seq-based View/Blueprint API, 10-arity, faster Get

This release reshapes the public iteration API around Go 1.23+ iterators,
extends generic arity from 8 to 10 components, and shaves 8.4% off the
GetComponent hot path.

Highlights
----------
* View.All yields SoA pages (iter.Seq) — inner loop on the caller side,
  full SoA layout exposed for SIMD-friendly access.
* View.Filter yields iter.Seq2[int, ...] — index correlates results with
  the input slice and surfaces skipped entities for free.
* Blueprint.Create(n) is batch-based — page-shaped slices for in-place
  initialization.
* View9, View10 and matching blueprints.
* View0.Filter for archetype membership checks.

Performance (Apple M1 Max, 0 allocs/op on all hot paths)
--------------------------------------------------------
* Get Component:  5.13 -> 4.70 ns/op  (-8.4%)
* View.Filter:    4.22 ns/ent (1 comp) ... 10.93 ns/ent (10 comp)
* View.All:       0.34 ns/ent (View0) ... 1.96 ns/ent (View10)
* Batch Create:   10-25 ns/ent (1-10 comp, batches of 1024)

Breaking changes
----------------
Signatures of View.All, View.Filter, Blueprint.Create and GetComponent
changed. See CHANGELOG.md [1.3.0] for the full migration guide.
