- Route Linux sandbox test setup through the shared exec request path.
- Drop dependencies that became unnecessary after the cleanup.

## What
Fix bash command parsing to accept double-quoted strings that contain
literal newlines so execpolicy can match allow rules.
## Why
Allow rules like [git, commit] should still match when commit messages
include a newline in a quoted argument; the parser currently rejects
these strings and falls back to the outer shell invocation.
## How
- Validate double-quoted strings by ensuring all named children are
string_content and then stripping the outer quotes from the raw node
text so embedded newlines are preserved.
- Reuse the helper for concatenated arguments.
- Ensure large SI suffix formatting uses the caller-provided locale
formatter for grouping.
- Add coverage for newline-containing quoted arguments.
Fixes#9541.
## Tests
- cargo test -p codex-core
- just fix -p codex-core
- cargo test -p codex-protocol
- just fix -p codex-protocol
- cargo test --all-features
- In the bottom line of the TUI, print the number of tokens to 3 sigfigs
with an SI suffix, e.g. "1.23K".
- Elsewhere where we print a number, I figure it's worthwhile to print
the exact number, because e.g. it's a summary of your session. Here we print
the numbers comma-separated.
