docs: use Arkade terminology, remove stray "Ark" protocol references

[tiero]

Replace standalone "Ark" with "Arkade" in comments, docs, and example
contract source where it referred to Arkade's own server/node/runtime/
operator. Keeps the established VTXO output-format token and the real
github.com/arkade-os/contract-sdk-go/ark Go package import untouched.

Walkthrough

This PR systematically updates terminology across the codebase from "Ark" to "Arkade." Changes span user documentation (README, specification, examples), library comments (IR, code generation targets, validator), and generated code templates with corresponding test assertion updates.

Changes

Ark to Arkade terminology update

Layer / File(s)	Summary
User-facing documentation README.md, docs/ArkadeKitties.md, docs/arkade-primitives-spec.md	README VTXO placeholder resolution, ArkadeKitties system description, and primitives spec Phase 7 comment are updated to reference "Arkade" instead of "Ark".
Core library and example comments arkade-bindgen/src/ir.rs, arkade-bindgen/src/targets/go.rs, arkade-bindgen/src/targets/typescript.rs, src/validator/mod.rs, examples/htlc.ark, examples/single_sig.ark, examples/threshold_multisig_htlc.ark	Field documentation, code generation comments, validator module docs, and example contract renewal comments are updated to reference "Arkade server" and "Arkade node" instead of "Ark".
Generated code and test assertions playground/codegen.js, arkade-bindgen/tests/go_test.rs, arkade-bindgen/tests/typescript_test.rs, tests/asm_structural_test.rs	Code generation templates and test assertions updated to expect witness comments with "Arkade server" terminology; test comments reference "Arkade operator".

Review: docs terminology rename (Ark → Arkade)

Verdict: APPROVE ✅

Reviewed the full diff across all 14 files and cross-checked remaining ark/Ark references in the codebase.

What this PR does

Pure docs/comments rename: standalone "Ark" → "Arkade" in comments, docstrings, example contract comments, and markdown docs. No logic, no API, no codegen output changes.

Verified correct

• Go package paths preserved: github.com/arkade-os/contract-sdk-go/ark, ark.Contract, ark.WitnessStack, ark.Raw, etc. are all real Go identifiers — correctly left untouched.
• .ark file extension preserved: The language extension is .ark, not .arkade — correctly untouched.
• VTXO token preserved: As stated in the PR description.
• No remaining stray \bArk\b: Grepped the full tree on the PR branch — zero hits for standalone capitalized "Ark" outside of Go package identifiers.
• go.rs:141-144 reformatting: The format! macro was split across lines (rustfmt style). Output is identical — verified by reading the full function.
• Test assertions updated in lockstep: go_test.rs:43 and typescript_test.rs:45 both updated to assert the new "Arkade server" string. Tests will catch any drift.
• playground/codegen.js updated in all three places: Lines 166, 258, 267 — consistent with the Rust codegen targets.

Cross-repo impact

None. This PR changes only comments, docstrings, and documentation. No public API, type, proto, or generated output is modified. Downstream SDKs and consumers are unaffected.

Protocol-critical

Not applicable — no protocol logic touched.
