Improve client library README wording and formatting

[tilo-14]

Minor improvements to clarity and consistency in the client library README:

• Change 'has only one' to 'offers one' for better tone
• Add hint block around PackedAccounts deduplication explanation for better visibility
• Add missing period in preAccounts description
• Remove redundant notes for cleaner documentation

Follow-up to PR #9 with additional documentation polish.

Summary by CodeRabbit

• Documentation
  • Reorganized client library documentation sections for improved clarity
  • Updated code examples across multiple languages to reflect current API usage
  • Streamlined system account configuration guidance
  • Enhanced overall content consistency and readability

Walkthrough

Documentation rewrite for the compressed PDA client library README, including textual refinement, reorganization of system account configuration sections, code example updates reflecting API terminology changes, and method signature adjustments in Rust examples.

Changes

Cohort / File(s)	Summary
Documentation: Client Library README zk-compression-docs/compressed-pdas/client-library/README.md	Substantial rewrite: semantic tightening of Rust/TypeScript sections, expanded hints on PackedAccounts behavior, consolidated system account configuration guidance, replaced code examples with updated API terminology (e.g., program::ID instead of program_create::ID), and reorganized PackTree and PackOutputState guidance with unified function calls.

Estimated code review effort

🎯 3 (Moderate) | ⏱️ ~20 minutes

Areas requiring extra attention:

• Verify all code example snippets correctly reflect current API usage, particularly SystemAccountMetaConfig::new() constructor and program identifier changes
• Cross-check reorganized sections for logical flow and consistency between Rust and TypeScript guidance
• Confirm internal deduplication behavior described in expanded hints aligns with actual implementation
• Validate terminology shifts (e.g., Anchor-native vs native workflows) are accurate and consistently applied throughout

Possibly related PRs

🔇 Additional comments (6)

zk-compression-docs/compressed-pdas/client-library/README.md (6)

126-126: Wording improvement aligns with PR objectives.

The change from "has only one client library" to "offers one client library" reads more positively and is consistent with the stated documentation polish goals.

---

695-715: Enhanced PackedAccounts documentation with improved clarity and deduplication hint.

The addition of the hint block (lines 711-715) effectively highlights the internal deduplication behavior with concrete examples. This increases discoverability of an important implementation detail. The section structure clearly describes the three account sections and their purposes.

---

861-873: Rust naming conventions correctly applied.

The updates to use snake_case (pre_accounts, system_accounts, tree_accounts) properly align the documentation with Rust idioms and improve consistency with the actual Rust SDK API surface.

---

963-963: Added clarification improves instruction specificity.

The text "For Anchor Create instructions" correctly restricts the scope of the following section (lines 961–982) to Anchor-only workflows, helping readers distinguish this from the already-bundled output handling in Update/Close/Reinit operations documented earlier. This reduces ambiguity.

---

887-893: No refactoring required—identifiers serve different purposes.

These represent intentional divergence, not an incomplete refactor:

• Line 202 (program_create::ID): Test harness identifier used in ProgramTestConfig for unit/integration testing with LiteSVM
• Line 887 (program::ID): Developer's actual program identifier used in production code to configure system accounts for proof verification

These are distinct concepts in different execution contexts (test framework vs. production code), so using different identifiers is correct design. The change at line 887 from program_create::ID to program::ID reflects moving from test configuration to production code patterns—exactly as it should be.

Likely an incorrect or invalid review comment.

---

889-889: This is a false positive—no action required.

All 55 code blocks in the document follow the same pattern: {% code %} wrappers directly contain markdown fences with no surrounding blank lines. Since these fences are nested within Gitbook-specific syntax (not document-level markdown), they don't trigger MD031's blank-line requirement. The document structure is consistent and correct.

Likely an incorrect or invalid review comment.
