## Summary
This is a purely mechanical refactor of `OtelManager` ->
`SessionTelemetry` to better convey what the struct is doing. No
behavior change.
## Why
`OtelManager` ended up sounding much broader than what this type
actually does. It doesn't manage OTEL globally; it's the session-scoped
telemetry surface for emitting log/trace events and recording metrics
with consistent session metadata (`app_version`, `model`, `slug`,
`originator`, etc.).
`SessionTelemetry` is a more accurate name, and updating the call sites
makes that boundary a lot easier to follow.
## Validation
- `just fmt`
- `cargo test -p codex-otel`
- `cargo test -p codex-core`
## Summary
Codex discovered this one - shell_snapshot tests were breaking on my
machine because I had a multiline env var. We should handle these!
## Testing
- [x] existing tests pass
- [x] Updated unit tests
Fixes#9559.
When `shell_snapshot` runs, it may execute user startup files (e.g.
`.bashrc`). If those files read from stdin (or if stdin is an
interactive TTY under job control), the snapshot subprocess can block or
receive `SIGTTIN` (as reported over SSH).
This change explicitly sets `stdin` to `Stdio::null()` for the snapshot
subprocess, so it can't read from the terminal.
Regression test added that would hang/timeout without this change.
Tests: `ulimit -n 4096 && cargo test -p codex-core`.

This PR adds 2 defensive mechanisms for shell snapshotting:
* Filter out invalid env variables (containing `-` for example) without
dropping the whole snapshot
* Validate the snapshot before considering it as valid by running a mock
command with a shell snapshot
Clean all shell snapshot files corresponding to sessions that have not
been updated in 7 days
Those files should never leak. The only known cases were it can leak are
during non graceful interrupt of the process (`kill -9, `panic`, OS
crash, ...)
