• [codex] Remove async_trait from first-party code (#27475)

  ## Why
  
  First-party async traits should expose their `Send` contracts explicitly
  without requiring `async_trait`. This completes the migration pattern
  established in #27303 and #27304.
  
  ## What changed
  
  - Replaced the remaining first-party `async_trait` traits with native
  return-position `impl Future + Send` where statically dispatched and
  explicit boxed `Send` futures where object safety is required.
  - Kept implementations behavior-preserving, outlining existing async
  bodies into inherent methods where that keeps the diff reviewable.
  - Removed all direct first-party `async-trait` dependencies and the
  workspace dependency declaration.
  - Added a cargo-deny policy that permits `async-trait` only through the
  remaining transitive wrapper crates.
  - Updated `rand` from 0.8.5 to 0.8.6 to resolve RUSTSEC-2026-0097 and
  keep the full cargo-deny check passing.
  
  ## Validation
  
  - `just test -p codex-exec-server`: 216 passed, 2 skipped.
  - `just test -p codex-model-provider`: 39 passed.
  - `just test -p codex-core` and `just test`: changed tests passed;
  remaining failures are environment-sensitive suites unrelated to this
  migration.
  - `cargo deny check`
  - `just fix`
  - `just fmt`
  - `cargo shear`
  - `just bazel-lock-check`

• Add remote thread config loader protos (#18892)

  ## Why
  
  Thread-scoped config needs a stable boundary between the app/session
  owner and the config stack. Instead of having call sites manually copy
  thread config fields into individual overrides, this adds the proto and
  Rust plumbing needed for a `ThreadConfigLoader` implementation to return
  typed sources that can be translated into ordinary config layer entries.
  
  Keeping the remote payload typed also makes precedence easier to reason
  about: session-owned thread config maps back to the existing session
  config source, while user-owned thread config is represented separately
  without introducing a new config-layer source until it has TOML-backed
  fields.
  
  ## What changed
  
  - Added the `codex.thread_config.v1` protobuf service and generated Rust
  module for loading thread config sources.
  - Added `RemoteThreadConfigLoader`, which calls the gRPC service, parses
  `SessionThreadConfig` / `UserThreadConfig`, and validates provider
  fields such as `wire_api`, auth timeout, and absolute auth cwd.
  - Added proto generation tooling under
  `config/scripts/generate-proto.sh` and
  `config/examples/generate-proto.rs`.
  - Added `ThreadConfigLoader::load_config_layers`, plus static/no-op
  loader helpers, so tests and callers can use the same typed loader
  interface while config-layer translation stays centralized.
  
  ## Verification
  
  - `cargo test -p codex-config thread_config`
