At over 7,000 lines, `codex-rs/core/src/config/mod.rs` was getting a bit
unwieldy.
This PR does the same type of move as
https://github.com/openai/codex/pull/12957 to put unit tests in their
own file, though I decided `config_tests.rs` is a more intuitive name
than `mod_tests.rs`.
Ultimately, I'll codemod the rest of the codebase to follow suit, but I
want to do it in stages to reduce merge conflicts for people.
## Summary
- reduce the SQLite-backed log retention window from 90 days to 10 days
## Testing
- just fmt
- cargo test -p codex-state

#### What
Add structured `@plugin` parsing and TUI support for plugin mentions.
- Core: switch from plain-text `@display_name` parsing to structured
`plugin://...` mentions via `UserInput::Mention` and
`[$...](plugin://...)` links in text, same pattern as apps/skills.
- TUI: add plugin mention popup, autocomplete, and chips when typing
`$`. Load plugin capability summaries and feed them into the composer;
plugin mentions appear alongside skills and apps.
- Generalize mention parsing to a sigil parameter, still defaults to `$`

Builds on #13510. Currently clients have to build their own `id` via
`plugin@marketplace` and filter plugins to show by `enabled`, but we
will add `id` and `available` as fields returned from `plugin/list`
soon.
####Tests
Added tests, verified locally.
This branch:
* Avoid flushing DB when not necessary
* Filter events for which we perfom an `upsert` into the DB
* Add a dedicated update function of the `thread:updated_at` that is
lighter
This should significantly reduce the DB lock contention. If it is not
sufficient, we can de-sync the flush of the DB for `updated_at`
## Summary
- move sqlite log reads and writes onto a dedicated `logs_1.sqlite`
database to reduce lock contention with the main state DB
- add a dedicated logs migrator and route `codex-state-logs` to the new
database path
- leave the old `logs` table in the existing state DB untouched for now
## Testing
- just fmt
- cargo test -p codex-state
