feat(permission): user-facing permission presets — one Permissions select over the two knobs

Browse Source 
A preset names a bundle of the two mechanism knobs — request =
workspace-write + ask, yolo = danger-full-access + never — so the editor
shows ONE 'Permissions' select where the sandbox-mode and approval-policy
tiers stay orthogonal capabilities (the Codex /approvals shape: presets over
two dials). ctx.permission (dsh-permission) owns the config-defined table,
validates the default preset's bundle against the composed knob defaults at
load (fails loud), and writes a switch THROUGH: one log-only
permission/preset event (the audit fact reverse-mapping cannot recover —
the planned 'agent' preset shares request's knob values and differs only in
composed policy) plus each knob event via its own setter, deduped — a
net-zero switch appends nothing. Every knob consumer keeps reading its own
fold, untouched.

The current preset DERIVES from the effective knob values — the fold breaks
bundle ties, a knob state outside the table is the reserved 'custom' value
(a state, not an error: shown while it holds, switchable FROM, never a
target), and defaultPreset disappears (zero-event state reverse-maps from
the composition defaults).

The ACP bridge drops the two per-knob selects for the one preset select
(advertised only when ctx.permission is composed); pending/anchor/no-op
semantics carry over unchanged, with the no-op echo acknowledged before
vocabulary validation so a client re-pushing a derived 'custom' current
never errors. The sandbox variant example composes the
service with a workspace-write default; the permission-switching,
escalation-approved and escalation-rejected scenarios are re-recorded under
it (escalations now target an outside-workspace /tmp path under
danger-full-access, self-cleaning) and config-options is re-authored on the
single-select wire.

## `ctx.permission` — `PermissionService`
The permission service (`ctx.permission`). Owns the deployment's preset table and THE write path for preset switches; presentation layers (the ACP bridge's single `Permissions` select) advertise names and call set. Composing it REQUIRES both mechanism knobs — a confining `ctx.bash` executor and the `ctx.approval` seam. A knob state matching no table entry is not an error but the derived CUSTOM_PRESET state: shown as the current value, never a switch target.

## `ctx.sandbox` — `SandboxProvider` (abstract seam)
Abstract process-sandbox service. Subclass, implement confine, and load the subclass as a plugin — it registers as `ctx.sandbox` (one implementation per context; loading a second throws, cordis' standard duplicate-service behavior).
