fix(10-02b): wire availableTools from runtime catalog at AppDelegate

Plan 10-02b / B-01 root-cause fix.

App/AppDelegate.swift:1274 previously constructed AgentOrchestrator
with `availableTools: []` — a hardcoded empty array. The 2026-05-07
live verification of Plan 10-02 surfaced this as the substrate bug
silencing every tool call across the agent: get_time, get_clipboard,
run_applescript, search_memory, forget_fact, vision tools, and the
four Phase 10-01 self-knowledge tools (list_audio_devices,
get_active_audio_route, get_self_state, list_camera_devices).

The model saw the system-prompt preamble naming tools but had no
schemas in the API tools[] field, so it hallucinated JSON tool
definitions into chat ("I'll check that for you. {\"name\": \"get_active_audio_route\", \"arguments\": {}}")
instead of dispatching real tool_use blocks.

Fix: source the catalog lazily via the new
`availableToolsResolver:` parameter from BOTH:
  - mcpRuntime.client.toolCatalog() — stdio helper tools
  - inProcessToolRegistry.toolSchemas() — memory + self-knowledge tools

The resolver fires once per outer-loop iteration in
AgentOrchestrator.runTurnLoop, NOT per stream event. By the time the
user submits their first turn, the install-order chain
  installMemory → installVision → installAgent → installVoice
                                              → installSelfKnowledgeTools
has populated all 7 in-process tools and all 3 stdio tools (10 total
catalog entries) — no install-order coupling needed at construction
time.

Verification:
- bash scripts/check-app-builds.sh PASS
- All 16 standalone boundary gates PASS
- Live re-verification of AC-05 ("What microphone are you using?")
  is the human-verify gate; see Live Verification section in
  10-02b-SUMMARY.md.
