Felipe Coury 8d398d3c52 feat(tui): add vim text object bindings (#24382)
## Why

Vim mode currently supports some normal-mode operators and motions, but
common text-object combinations like `ciw`, `daw`, `di(`, and
quote/bracket variants are still missing. That makes the composer feel
incomplete for users who expect operator + text object editing to work
inside prompts.

Closes #21383.

## What Changed

- Add Vim pending-state support for operator/text-object sequences.
- Add `c` as a normal-mode operator for text objects, so combinations
like `ciw` delete the object and enter insert mode.
- Support word, WORD, delimiter, and quote text objects:
  - `iw`, `aw`, `iW`, `aW`
  - `i(`, `a(`, `i)`, `a)`, `ib`, `ab`
  - `i[`, `a[`, `i]`, `a]`
  - `i{`, `a{`, `i}`, `a}`, `iB`, `aB`
  - `i"`, `a"`, `i'`, `a'`, `i\``, `a\``
- Add configurable keymap entries and keymap picker coverage for the new
Vim text-object context.
- Regenerate the config schema and update keymap picker snapshots.

## How to Test

Manual smoke test:

1. Start Codex with Vim composer mode enabled.
2. Type a draft such as:
   ```text
   alpha beta gamma
   call(foo[bar], {"x": "hello world"})
   say "one \"two\" three" now
   ```
3. Put the cursor on `beta`, press `ciw`, and confirm `beta` is removed
and the composer enters insert mode.
4. Escape back to normal mode, put the cursor on `gamma`, press `daw`,
and confirm `gamma` plus surrounding whitespace is removed.
5. Put the cursor inside `foo[bar]`, press `di[`, and confirm only `bar`
is removed.
6. Put the cursor inside `call(...)`, press `da(`, and confirm the whole
parenthesized section is removed.
7. Put the cursor inside the quoted text, press `ci"`, and confirm the
quote contents are removed and insert mode starts.
8. Verify cancellation does not edit text: press `d` then `Esc`, and
press `d` then `i` then `Esc`.

Targeted tests:

- `cargo test -p codex-tui --lib vim_`
- `cargo nextest run -p codex-tui keymap_setup::tests`

Additional local checks:

- `just write-config-schema`
- `just fmt`
- `just fix -p codex-tui`
- `git diff --check`
- `cargo insta pending-snapshots --manifest-path tui/Cargo.toml`

Local full-suite note: `just test -p codex-tui` ran to completion. The
keymap snapshot failures were expected and accepted. Two unrelated
guardian feature-flag tests still fail locally:
-
`app::tests::update_feature_flags_disabling_guardian_clears_review_policy_and_restores_default`
-
`app::tests::update_feature_flags_disabling_guardian_clears_manual_review_policy_without_history`

`just argument-comment-lint` is currently blocked locally by Bazel
analysis before the lint runs because `compiler-rt` has an empty
`include/sanitizer/*.h` glob in the local Bazel cache. The touched Rust
diff was manually inspected for opaque positional literals.
