feat: preserve accumulated schema and desktop improvements

[1jehuang]

Summary

• preserve accumulated desktop2 workspace, scene, transcript, and math-rendering improvements
• consolidate OpenAI schema cleanup into the shared schema-dialect engine with recovery coverage
• keep provider, renderer, notification, and confidence-test formatting changes consistent
• add the desktop2 image-paste reapplication helper

Verification

• cargo fmt --all -- --check
• cargo test --profile selfdev -p jcode-schema-dialect -p jcode-render-core -p jcode-provider-core -p jcode-provider-openai-runtime
• cargo check --profile selfdev -p jcode-desktop2

Greptile Summary

This PR adds shared provider schema cleanup and carries forward desktop2 workspace and rendering improvements. The main changes are:

• Shared schema-dialect normalization and recovery for provider tool schemas.
• OpenAI schema cleanup moved onto the shared dialect engine.
• Desktop2 workspace row and page rendering improvements.
• Native inline math rendering in desktop2 transcripts.
• Image-paste reapplication helper and related desktop2 wiring.

Confidence Score: 4/5

Mostly safe to merge after the inline math reveal bug is fixed.

One contained issue affects desktop2 streaming display for inline math. Schema dialect and workspace changes reviewed without another concrete bug.

T-Rex Logs

What T-Rex did

• Ran a Rust harness to reproduce the reveal accounting for inline math under a partial streaming block reveal, and confirmed the glyph counts block_glyphs_including_inline_math=12 and inline_formula_glyphs=2.
• Observed that preserving reveal accounting would draw only 1 formula glyph, while the scene inline draw path using f64::INFINITY drew both glyphs.
• Inspected verification artifacts, including the Rust harness source and the cargo run log used to validate the inline math reveal accounting.
• Ran cargo test across multiple crates; all targeted tests reported ok for provider core, OpenAI runtime, render core, schema dialect, integration tests, and doc tests.
• Noted formatting and checks status: cargo fmt --all -- --check failed due to missing cargo-fmt/rustfmt, while cargo check desktop2 and the broader test suite completed; a pr-verification-summary log captured the results.

### Issue 1
crates/jcode-desktop2/src/scene.rs:1411
**Preserve reveal accounting**
`block.glyphs` now includes `inline_math` glyphs, but the draw path always renders each inline formula with `f64::INFINITY`. During streaming, as soon as the surrounding block has any reveal budget, every inline formula in that visible block is painted completely, while `drawn_glyphs += block.glyphs` still charges those math glyphs to the reveal budget. This breaks the existing per-glyph reveal contract for messages containing inline math.

For each issue above, determine whether it is valid and should be fixed. If so, fix it directly.

Artifacts

Repro: Rust harness source for inline math reveal accounting

• Evidence file captured while the check ran.

Repro: cargo run output showing complete inline formula draw under partial reveal

• The full command output behind this check.
