Rename CodexRequest to ExecutionRequest

[MGudgin]

Summary

Renames the Rust struct CodexRequest to ExecutionRequest across the workspace.

CodexRequest is the validated, internal execution model that Raw* config-parser structs are mapped to and that ScriptRunner implementations consume. The Codex prefix is a historical holdover and no longer reflects what the type represents. ExecutionRequest matches the "request handed to a ScriptRunner for execution" mental model and keeps the layered Policy → Config → Runner vocabulary already used in the codebase clean:

Layer	Type
High-level user intent (TS SDK)	SandboxPolicy
Wire format (TS → JSON)	ContainerConfig
Permissive parse (Rust)	Raw* structs
Validated internal form (Rust)	ExecutionRequest

Changes

• Renamed the struct definition and all references across the Rust workspace (303 textual replacements across 40 files).
• Updated documentation that referenced the old name (docs/versioning.md, docs/authoring-a-new-feature.md, docs/state-aware-lifecycle/*, docs/bwrap-support/*, docs/diagnostics.md, docs/base-process-container/guide.md, docs/wsl/*, docs/nanvix-microvm/*, docs/isolation-session/initial-bringup-plan.md, and .github/copilot-instructions.md).
• Applied cargo fmt so a few now-longer signature lines wrap correctly.

Verification

Ran from src/:

• cargo fmt --all -- --check — clean
• cargo clippy --workspace --all-targets -- -D warnings — clean
• cargo build --workspace — clean
• cargo test --workspace --exclude wxc_e2e_tests — all tests pass

Closes #446

Pull request overview

This pull request renames the Rust validated internal execution model CodexRequest to ExecutionRequest across the Rust workspace and updates documentation references to match, aligning the type name with its role as the request consumed by ScriptRunner implementations.

Changes:

• Renamed CodexRequest → ExecutionRequest in the core model and updated all Rust call sites (runners, dispatcher, parser, validators, tests).
• Updated docs and repo instructions to reference ExecutionRequest instead of the historical CodexRequest name.
• Applied formatting adjustments where signatures/comments wrapped due to the rename.
