[codex] Warn clearly when code mode output is truncated (#28467 )

## Summary

- make `formatted_truncate_text` prepend `Warning: truncated output
(original token count: N)` above the existing `Total output lines`
header
- update direct formatter, unified-exec, user-shell, and code-mode
expectations
- add core unit coverage that runs in Bazel without requiring the
skipped V8-backed code-mode integration suite

## Validation

- `cargo test -p codex-utils-output-truncation -- --nocapture` (17
passed)
- `cargo test -p codex-core --lib
truncated_text_output_starts_with_warning -- --nocapture`
- `cargo test -p codex-core --test all
clamps_model_requested_max_output_tokens_to_policy -- --nocapture` (2
passed)
- `cargo test -p codex-core --test all
unified_exec_formats_large_output_summary -- --nocapture`
- `cargo test -p codex-core --test all
user_shell_command_output_is_truncated_in_history -- --nocapture`
- Bazel CI exercises the shared formatter and downstream integration
expectations

add encryptedcontent to functioncalloutput (#23500 )

add new `EncryptedContent` variant to `FunctionCallOutputContentItem`
ahead of standalone websearch.

we need to be able to receive and pass encrypted function call output
from the new web search endpoint back to responsesapi, as we cannot
expose direct search results.

Disable empty Cargo test targets (#21584 )

## Summary

`cargo test` has entails both running standard Rust tests and doctests.
It turns out that the doctest discovery is fairly slow, and it's a cost
you pay even for crates that don't include any doctests.

This PR disables doctests with `doctest = false` for crates that lack
any doctests.

For the collection of crates below, this speeds up test execution by
>4x.

E.g., before this PR:

```
Benchmark 1: cargo test     -p codex-utils-absolute-path     -p codex-utils-cache     -p codex-utils-cli     -p codex-utils-home-dir     -p codex-utils-output-truncation     -p codex-utils-path     -p codex-utils-string     -p codex-utils-template     -p codex-utils-elapsed     -p codex-utils-json-to-toml
  Time (mean ± σ):      1.849 s ±  4.455 s    [User: 0.752 s, System: 1.367 s]
  Range (min … max):    0.418 s … 14.529 s    10 runs
```

And after:

```
Benchmark 1: cargo test     -p codex-utils-absolute-path     -p codex-utils-cache     -p codex-utils-cli     -p codex-utils-home-dir     -p codex-utils-output-truncation     -p codex-utils-path     -p codex-utils-string     -p codex-utils-template     -p codex-utils-elapsed     -p codex-utils-json-to-toml
  Time (mean ± σ):     428.6 ms ±   6.9 ms    [User: 187.7 ms, System: 219.7 ms]
  Range (min … max):   418.0 ms … 436.8 ms    10 runs
```

For a single crate, with >2x speedup, before:

```
Benchmark 1: cargo test -p codex-utils-string
  Time (mean ± σ):     491.1 ms ±   9.0 ms    [User: 229.8 ms, System: 234.9 ms]
  Range (min … max):   480.9 ms … 512.0 ms    10 runs
```

And after:

```
Benchmark 1: cargo test -p codex-utils-string
  Time (mean ± σ):     213.9 ms ±   4.3 ms    [User: 112.8 ms, System: 84.0 ms]
  Range (min … max):   206.8 ms … 221.0 ms    13 runs
```

Move string truncation helpers into codex-utils-string (#15572 )

- move the shared byte-based middle truncation logic from `core` into
`codex-utils-string`
- keep token-specific truncation in `codex-core` so rollout can reuse
the shared helper in the next stacked PR
