refactor(daemon): stop importing the commands barrel through src/runtime.ts

[thymikee]

Purpose

Five daemon files import src/runtime.ts, which imports the command barrel with a value import:

// src/runtime.ts
import { bindCommands, type BoundAgentDeviceCommands } from './commands/index.ts';

The value closure of src/runtime.ts is 122 files, 48 of them under src/commands/. The daemon's total value closure is 717 files and carries 121 src/commands/** files — roughly the entire commands zone (140 files, 21k LOC) — plus 17 root flat files. The daemon loads a command surface it does not dispatch through, and every change in commands is potentially a daemon-restart-cost event.

Umbrella: #2545. Chosen first because it is the only child that changes what the daemon actually loads, and because #2469 (eager-closure budget tolerance) is unblocked by cutting closure, not by adding budget.

Required behavior

1. src/runtime.ts keeps its public shape: AgentDevice, createAgentDevice, createMemorySessionStore, localCommandPolicy, restrictedCommandPolicy, and the re-exported command types. No consumer-side API change is part of this issue.
2. Daemon consumers of src/runtime.ts take the specific declarations they use through their owning module or contract, not through the runtime facade. Determine the used symbol set per importer before choosing the seam; do not invent an interface wider than the symbols in use.
3. The barrel src/commands/index.ts either stops being the value entry for runtime binding, or the binding moves to the composition root that needs it. One construction path, no second registry.

Completion conditions

• Value-only transitive closure from src/daemon/** contains zero files under src/commands/. Measured with a probe over scripts/layering/model.ts as described in the parent, and reported in the PR.
• src/runtime.ts has no value edge into src/commands/**, or is no longer reachable from src/daemon/** at all.
• No new eager work: the eager-import-closure budgets for the daemon entry surfaces do not rise.
• R4 stays 0, R5 stays 0, R6 does not grow past the ratchet.

Out of scope

• Repackaging src/commands as a workspace package. That decision needs the cli-schema orientation settled first (sibling child).
• Any change to the command descriptor registry or the command-registry package.

Dependencies

• None. Wave A, independent branch.

Closure measurement: the runtime.ts cut alone does not reach the completion condition

Probe over scripts/layering/model.ts (value edges only, static, from src/daemon/**) at e6f288012b:

cut	daemon closure	src/commands/** files
none (today)	719	121
src/runtime.ts → commands/index.ts only	662	75
that + the daemon's two cli-schema/command-schema.ts imports	584	0

The second path is src/daemon → src/cli-schema/command-schema.ts → src/commands/command-metadata.ts → src/commands/family/registry.ts → every command family. Two daemon files hold it, one symbol each:

• src/daemon/request-execution-scope.ts takes applyCommandDefaults. It resolves the full per-command schema, which is authored inside the command facets. Exactly one command declares defaults today (app, appsFilter), and src/cli/parser/args.ts already applies the same defaults on the CLI side.
• src/daemon/session-action-recorder.ts takes recordedFlagKeys. That function lives in src/commands/cli-grammar/flag-registry.ts and its closure is only the four flag-definitions-*.ts files plus flag-types.ts.

So "zero src/commands/** files" needs these two edges cut as well. Either this issue owns them (import recordedFlagKeys from the flag registry directly and take the daemon-side defaults application through something that does not resolve the whole facet table), or the condition is relaxed here and #2543 owns it. I have posted the same data on #2545 and #2543 so the sequencing is decided in one place.

Completion contract: the achievable floor is 34, not 0 — needs a decision before #2548 can close this

PR #2548 ships the src/runtime.ts cut. Measured value-only closure from src/daemon/**, with the change in place:

state	daemon closure	src/commands/**	commands LOC
before (9aa6465768)	717	121	19,659
after #2548	705	108	17,434
#2548 + #2543's two command-schema.ts edges	628	34	6,364

The issue's probe of 75 assumed nothing replaces the barrel. It cannot: the daemon calls capture.snapshot/diffSnapshot/screenshot, selectors.find/get/is/wait and interactions.gesture/click/press/fill/hover/settleObservation, so the 33-34 files implementing those three families return the moment a scoped binder replaces createAgentDevice. That residue is the daemon's own dispatch surface, not accidental coupling.

Two consequences:

1. "Zero src/commands/** in the daemon closure" is only reachable if the daemon stops executing commands in-process. Proposed replacement condition: the daemon reaches only the command families it dispatches through (capture, selectors, interactions), imports no all-family barrel, and holds 0 src/commands files outside those families plus whatever refactor(cli-schema): orient the schema layer below commands #2543 resolves.
2. recordedFlagKeys cannot be imported from commands/cli-grammar/flag-registry.ts by the daemon. That is a direct daemon → commands value edge and R2 commands-floor rejects it (scripts/layering/zone-policy.ts:47). The symbol has to move down to packages/command-registry, which is refactor(cli-schema): orient the schema layer below commands #2543's "flag grammar goes down" step — so this issue should not own that edge.

Suggest: #2548 merges as the runtime split, the condition above replaces the zero, and the remaining 74-file path is #2543's.

[thymikee]

Closing on the decision above: the completion condition is the dispatched-families invariant, not zero. #2548 delivered the runtime split, #2562 cut the second path through cli-schema/command-schema.ts. At 775163bb35 the daemon reaches src/commands only through src/runtime-command-surface.ts, and the closure holds 34 files (30 under */runtime/**, 4 shared runtime helpers), no facet, reader, formatter, or barrel. src/runtime.ts keeps its public shape. Umbrella body updated with the same wording.
