feat(agent): add gpt56 profile for GPT-5.6 Sol, Terra, and Luna
Codex drives the GPT-5.6 models with a much narrower tool set than the
other OpenAI models: a shell, `apply_patch`, and `update_plan`. It has no
file-read, file-write, grep, glob, or fetch tool at all -- reading and
searching go through the shell, and every write goes through
`apply_patch`. Offering 5.6 fabro's extra tools advertises affordances its
instructions never mention, so this adds a profile that registers only
what Codex does.

The profile is selected per model via `agent_profile = "gpt56"` on the six
5.6 rows (three each on `openai` and `openrouter`), following the existing
Kimi-over-a-gateway pattern. Every other model on those providers keeps
its provider default, with no code branch and no version sniffing.

- `ToolVocabulary::Codex` renames `shell` to `shell_command`; a strum
  alias keeps `from_any_name` resolving it to `NativeTool::Shell`, so
  permissions, categories, and telemetry still key on the canonical name.
- `shell_command` gains `workdir`, passed to the `cwd` argument
  `execute_shell_command` already accepted, with Codex's "always set
  `workdir`, do not `cd`" guidance.
- `prompts/gpt56.md.j2` is adapted from Codex's 5.6 `base_instructions`,
  which are byte-identical across Sol, Terra, and Luna. A header comment
  records provenance and the departures fabro's harness forces.

This is an alignment-only pass: it matches Codex's tool contract while
keeping direct tool calls. Codex actually drives 5.6 in code mode, with a
single `exec` tool taking JavaScript and every other tool reached through
a `tools` object inside a V8 isolate. That is deliberately out of scope.

Luna's `multi_agent_version: v1` (vs v2 on Sol and Terra) is also out of
scope. It only changes the sub-agent tool set, which fabro registers from
the caller rather than the profile, and fabro's current set matches
neither version exactly.

Two server cancel-timing tests are adjusted. `gpt-5.6-sol` is the
`openai` provider's default model, so runs that name no model now build a
3-tool profile instead of an 8-tool one and reach their first stage
sooner. `full_http_lifecycle_cancel` asserted `status.kind == "blocked"`
at the instant of cancel, which the worker is free to change the moment it
is signaled; it now accepts either live state, matching the tolerance its
own comment already documents for `pending_control`.
