Fix Rust client library description and close missing tab tags

[tilo-14]

Fixes from mintlify-docs branch:

• Clarify Rust has one client library (not 'combines tokens')
• Standardize hint block wording for consistency
• Add missing endtab tag to close Rust tab properly

@coderabbitai Please review the entire client library README.md file at zk-compression-docs/compressed-pdas/client-library/README.md for:

• GitBook syntax correctness
• Heading hierarchy
• Technical accuracy
• Documentation clarity

Walkthrough

The compressed PDAs client library documentation was refined to clarify the Rust SDK architecture. The Rust section now explicitly describes having one client library alongside a separate SDK for program-side development, replacing the previous phrasing about combining tokens in the client library.

Poem

📚 One library shines, two purposes gleam,
The docs now clarify the Rust SDK dream—
Program-side and client dance their own way,
Precision in prose brightens the day. ✨

125-211: Rust section update is clear and accurate; syntax is properly closed.

The change to line 126 successfully clarifies the Rust SDK architecture by explicitly stating there is "only one client library" with a separate SDK for program-side development. This removes ambiguity around the architecture. The {% endtab %} at line 211 properly closes the Rust tab block. The nested tab structure (lines 141-186 with Mainnet/Devnet/Localnet variants) is well-organized.

9-9: Heading hierarchy is well-structured and consistent.

The document follows a logical h1→h2→h3 hierarchy that aligns with the {% stepper %} structure. Each major step is an h2, with detailed subsections like "Optimize with Single Combined Proofs" (h3) providing proper nesting. This makes the document navigable and scannable for both readers and documentation systems.

Also applies to: 41-41, 216-216, 321-321, 429-429, 1072-1072, 1584-1584, 1783-1783, 1813-1813, 1895-1895

---

35-37: Hint blocks are well-standardized with clear formatting.

The document uses consistent GitBook hint syntax with three style variants (info, success, warning) appropriately placed. Hint blocks provide valuable context—linking to API docs, explaining implementation differences between Anchor and Native programs, or highlighting performance optimizations. The wording across hints is clear and purposeful; no standardization improvements are needed.

Also applies to: 50-52, 86-88, 208-210, 223-225, 227-229, 295-299, 329-331, 437-439, 565-570, 605-607, 671-673, 814-818, 841-845, 873-877, 911-915, 1010-1015, 1076-1080, 1841-1843

1-1812: Documentation is comprehensive, well-organized, and pedagogically sound.

This is an excellent client library guide that successfully balances breadth (covering Typescript and Rust) with depth (multiple configuration patterns, operation types, and optimization strategies). The progressive structure—from setup through full examples—helps readers build understanding incrementally. The Pack Accounts section (lines 687–1068) deserves special mention for its clarity in explaining a complex concept through visual hierarchies, parameter explanations, and operation-specific variations. Cross-language consistency (showing equivalent patterns in Typescript and Rust side-by-side) is a strong documentation practice.

---

1-7: YAML frontmatter and GitBook syntax are correct throughout.

The document properly uses GitBook's Markdown extensions: frontmatter defines metadata (title, description, hidden flag), {% stepper %} provides step-based navigation, {% tabs %}/{% endtabs %} handle multi-language content blocks, and hint blocks ({% hint %}) add contextual information. All blocks are properly opened and closed. The PR's objective to close missing tab tags has been successfully addressed.
