refactor: make vestigial runner-client/app-log dynamic imports static

[thymikee]

Problem

pnpm build warned:

[INEFFECTIVE_DYNAMIC_IMPORT] src/daemon/app-log.ts is dynamically imported by
src/daemon/request-platform-providers.ts but also statically imported by
session-observability.ts, session-teardown.ts — dynamic import will not move
module into another chunk.

Investigation

app-log.ts is await import()ed in request-platform-providers.ts but also
statically imported elsewhere, so the dynamic import splits nothing. Digging in,
this is a whole class of vestigial dynamic imports — rolldown only surfaces a
subset at a time, so fixing one reveals the next (runner-provider, then
runner-client).

Every flagged module is already eager in the daemon entry chunk
(internal/daemon.js) through static importers, so the await import() calls
defer nothing:

Module	Why it's already eager	Fix
app-log.ts	static in session-observability / session-teardown	static import
runner-provider.ts	static via runner-client	static import
runner-client.ts	static in ~20 daemon modules (session lifecycle, screenshot, selectors, record-trace, teardown)	static import

runner-client's await import()s lived in dispatch, dispatch-interactions,
transport, daemon-runtime, http-server (two of them re-importing on every
poll-loop iteration).

Why this is safe

• No import cycle — runner-client's 97-module static closure never reaches
  dispatch/server, so static imports can't introduce an init-order/TDZ bug.
• Byte-identical eager closures for every entry — the CLI stays at
  487,422 B with runner-client absent; only the daemon entry contains it,
  exactly as before.
• Forcing runner-client into its own chunk was considered and rejected: it
  dragged the full ~97 KB into the CLI's eager closure by defeating tree-shaking
  of one small constant the CLI references.

Result

• Build is warning-free (was 1 reported, ≥3 latent).
• Behavior unchanged: these modules were already loaded at daemon start; the
  no-op dynamic imports are just removed.
• pnpm typecheck, oxlint, and dispatch / runner / provider-scope /
  server-shutdown tests all pass.
