Description

wg show <task> reports concrete dated model ids like claude-opus-4-6, claude-sonnet-4-20250514, etc. when the user wrote claude:opus / claude:sonnet in config or CLI. That's wrong — we should pass the bare alias (opus, sonnet, haiku) to the claude CLI, which knows how to resolve to the current model on its end. Hardcoding dated ids in wg means we're forever chasing Anthropic's release cadence in our config.

Required mapping

Alias	Should resolve to (string passed to claude CLI)
`claude:opus`	`opus`
`claude:sonnet`	`sonnet`
`claude:haiku`	`haiku`

Yes, just the bare tier name. The claude CLI accepts these and resolves to current production models on its side. We should not be in the business of tracking which dated id is 'current.'

Fix

Find where the alias resolution happens (likely in src/models/ or src/config/ — grep for the existing dated ids claude-opus-4-6, claude-sonnet-4-20250514, claude-haiku-).
Replace the lookup table to map to the bare strings above.
wg show should display the bare alias (opus) for tasks created with claude:opus, NOT a dated id. If wg currently 'helpfully' canonicalizes to a dated id at task-creation time, stop doing that — store the alias as written and only resolve at spawn time when invoking claude CLI.
Add unit tests asserting the alias → 'opus' / 'sonnet' / 'haiku' bare-string mapping. The tests must NOT contain any dated id; if they do, drift will silently re-introduce the bug.
Document the bare-alias contract in a single source-of-truth comment + corresponding entry in docs/AGENT-SERVICE.md or wherever models are listed.

Additionally

Audit the codebase for any OTHER place that hardcodes dated model ids (claude-*-4-*, claude-*-202[0-9]-*-*). If found, replace with bare aliases or a single defaults constant.
Coordinator-launch surfaces (TUI dialog, IPC CreateCoordinator) should also show / pass bare aliases — user reported seeing --executor claude --model claude-opus-4-6 in the launch dialog.

Out of scope

Don't redesign the alias system; just stop hardcoding dated ids.
Don't change the alias names themselves (claude:opus etc. stay).

Validation

Failing tests first: test_alias_claude_opus_resolves_to_bare_opus, test_alias_claude_sonnet_resolves_to_bare_sonnet, test_alias_claude_haiku_resolves_to_bare_haiku, test_no_dated_model_ids_anywhere_in_source (grep src/ for 'claude--4-' regex; assert zero matches outside test fixtures and docs)
Implementation makes tests pass
cargo build + cargo test pass with no regressions
Manual: wg add 'test' --model claude:opus then wg show <id> reports opus (or claude:opus), NOT claude-opus-4-6 or any dated id
Manual: TUI new-coordinator dialog launch line shows --model opus not --model claude-opus-4-6

## Description

`wg show <task>` reports concrete dated model ids like `claude-opus-4-6`, `claude-sonnet-4-20250514`, etc. when the user wrote `claude:opus` / `claude:sonnet` in config or CLI. That's wrong — we should pass the **bare alias** (`opus`, `sonnet`, `haiku`) to the claude CLI, which knows how to resolve to the current model on its end. Hardcoding dated ids in wg means we're forever chasing Anthropic's release cadence in our config.

### Required mapping

| Alias            | Should resolve to (string passed to claude CLI) |
|------------------|--------------------------------------------------|
| `claude:opus`    | `opus`                                           |
| `claude:sonnet`  | `sonnet`                                         |
| `claude:haiku`   | `haiku`                                          |

Yes, just the bare tier name. The `claude` CLI accepts these and resolves to current production models on its side. We should not be in the business of tracking which dated id is 'current.'

### Fix

1. Find where the alias resolution happens (likely in src/models/ or src/config/ — grep for the existing dated ids `claude-opus-4-6`, `claude-sonnet-4-20250514`, `claude-haiku-`).
2. Replace the lookup table to map to the bare strings above.
3. `wg show` should display the bare alias (`opus`) for tasks created with `claude:opus`, NOT a dated id. If wg currently 'helpfully' canonicalizes to a dated id at task-creation time, stop doing that — store the alias as written and only resolve at spawn time when invoking claude CLI.

5. Document the bare-alias contract in a single source-of-truth comment + corresponding entry in docs/AGENT-SERVICE.md or wherever models are listed.

### Additionally

- Audit the codebase for any OTHER place that hardcodes dated model ids (`claude-*-4-*`, `claude-*-202[0-9]-*-*`). If found, replace with bare aliases or a single defaults constant.
- Coordinator-launch surfaces (TUI dialog, IPC CreateCoordinator) should also show / pass bare aliases — user reported seeing `--executor claude --model claude-opus-4-6` in the launch dialog.

### Out of scope

- Don't redesign the alias system; just stop hardcoding dated ids.
- Don't change the alias names themselves (`claude:opus` etc. stay).
