feat(pwsh): render pwsh calls as bash-shaped terminal cards in the Web UI

A completed pwsh foreground call now presents as the bash tool's terminal
card with the parsed exit-status pill instead of a generic console fence,
and the collapsed row classifies as the shell family (Pwsh title). The
marker-to-exit-status parse moves from dsh-tool-bash's private render
module into the @deepseek-ai/dsh-bash seam so both shell tools share one
inverse of the marker contract (the bash-env precedent). The Web UI needs
no per-tool code: the terminal-card bridge maps any card:'terminal' view.

Coverage: dsh-bash owns the parse edge cases; the tool-pwsh presenter
suite mirrors tool-bash's; the client row-model suite pins the Pwsh shell
row; the new keyless pwsh-terminal web lane seeds an authored session,
presents it through the real tool on replay, and pins the card golden.

TUI is out of scope: the TUI package was removed (ed30088adb), so the Web
surface is the only UI the gap affected; the roadmap proposal's stage 2
is updated accordingly.

 Two follow-up stages, each independently shippable. The former stage 2 (bash-tool parity twin) shipped with the [pwsh tool bash parity decision](../../implemented/feature/2026-08-02-pwsh-tool-bash-parity.md): `tool-pwsh` now mirrors `tool-bash` for foreground and background work minus the sandbox surface, shares the `DSH_*` environment through `dsh-bash-env`, and carries a keyless application snapshot of its assembled surface.
 
 1. **Windows default composition** — the shipped CLI compositions mount `dsh-pwsh-local` as the `ctx.bash` executor and `dsh-tool-pwsh` as the model-facing shell tool on Windows hosts (bash unmounted there), while POSIX hosts keep the bash stack. This is a composition/roster decision in `base.cordis.yml` and the surface overlays, gated by platform; it makes the shipped Windows experience PowerShell-native end to end.
-2. **pwsh TUI/GUI rendering** — the TUI and Web surfaces render pwsh output with PowerShell-aware presentation (native path display, `$env:` facts), the counterpart of the bash terminal cards. This is where terminal/console rendering conventions get a PowerShell twin.

 - A Windows host running the shipped `dsh` TUI/Web gets `pwsh` as its shell tool and PowerShell as the `ctx.bash` executor without configuration, and `bash` is absent from the model-visible roster there.
 - POSIX hosts are byte-for-byte unaffected (same roster, same executor).

 ## Risks
 
 - **Bash-dependent composition rows** — any shipped plugin that assumes `bash` semantics (hook bridges executing shell hooks, workspace tooling) must be audited per stage; the audit may force a staged rollout rather than one switch.
 - **Windows CI coverage gap** — unit coverage runs on Linux; Windows-only regressions in the pwsh stack surface through the Windows build/static lane and e2es, which must be extended per stage rather than assumed.
-- **Rendering conventions** — a PowerShell twin for terminal cards is a UI design decision with snapshot surface; deferring it (stage 2) keeps stage 1 shippable without UI churn.
