* fix: preserve wrapped tool errors in history replay

* fix: address review findings on PR #1639

- Simplify legacy error handling in rebuild_chat_messages_from_db:
  remove redundant "Error: " prefix since legacy errors already contain
  descriptive text (e.g. "Tool 'http' failed: timeout"). Both wrapped
  (new) and plain (legacy) errors now pass through as-is.
- Update existing test assertion to match simplified format.
- Restore error-path doc line on process_tool_result.

* fix: satisfy clippy on builder tool safety helper

-# User Management API
-
-DB-backed user management for multi-tenant IronClaw deployments. Covers admin user CRUD, per-user secrets provisioning, self-service profile, API token management, and usage reporting.
-
-## Authentication
-
-All endpoints require `Authorization: Bearer <token>`. Tokens are either:
-- **Env-var tokens** — configured via `GATEWAY_AUTH_TOKEN` (single-user) at startup
-- **DB-backed tokens** — created via `POST /api/tokens` or `POST /api/admin/users`
-
-DB tokens are SHA-256 hashed at rest; plaintext is returned exactly once at creation time.
-
-Auth is cached in a bounded LRU (1024 entries, 60s TTL). Suspending a user or revoking a token may take up to 60s to take effect.
-
-## Roles
-
-| Role | Scope |
-|------|-------|
-| `admin` | Full access to all endpoints |
-| `member` | Self-service profile + own token management only |
-
-Endpoints marked **Admin** return `403 Forbidden` for `member` role.
-
----
-
-## Admin: Users
-
-### POST /api/admin/users
-
-Create a new user. Returns the user record and a one-time plaintext API token.

-## Admin: Per-User Secrets
-
-Provision secrets on behalf of individual users. The primary use case is an application backend (acting as admin) that configures per-user credentials so each user's IronClaw agent can call back to external services.
-
-Secrets are encrypted at rest with AES-256-GCM using a per-secret HKDF-derived key. Plaintext values are **never returned** by any endpoint — they can only be used by the agent's tool system at runtime.
-
-### PUT /api/admin/users/{user_id}/secrets/{name}
-
-Create or update a secret for the specified user. If a secret with the same name already exists, it is overwritten.
-
-**Auth:** Admin
-
-**Path parameters:**
-
-| Param | Type | Notes |
-|-------|------|-------|
-| `user_id` | string | The user's ID |
-| `name` | string | Secret name (normalized to lowercase) |
-
-**Request body:**
-
-```json
-{
-  "value": "sk-live-abc123...",
-  "provider": "my-app-backend",
-  "expires_in_days": 90
-}
-```
-
-| Field | Type | Required | Notes |
-|-------|------|----------|-------|
-| `value` | string | yes | The secret value (encrypted at rest, never returned) |
-| `provider` | string | no | Tag for grouping (e.g. `"stripe"`, `"my-app"`) |
-| `expires_in_days` | integer | no | Auto-expire after N days; `null` = never |
-
-**Response:** `200 OK`
-
-```json
-{
-  "user_id": "550e8400-...",
-  "name": "my_app_callback_token",
-  "status": "created"
-}
-```
-
-**Errors:** `400` (missing value), `403` (not admin), `503` (secrets store not available)
-
-**Example — application backend provisioning a callback token:**
-
-```bash
-# Admin creates a user
-curl -X POST https://ironclaw.example.com/api/admin/users \
-  -H "Authorization: Bearer $ADMIN_TOKEN" \
-  -d '{"display_name": "Alice", "role": "member"}'
-# Response includes: {"id": "alice-uuid", "token": "alice-bearer-token", ...}
-
-# Admin provisions a per-user callback secret
-curl -X PUT https://ironclaw.example.com/api/admin/users/alice-uuid/secrets/app_callback_token \
-  -H "Authorization: Bearer $ADMIN_TOKEN" \
-  -d '{"value": "per-user-jwt-for-alice", "provider": "my-app"}'
-
-# Now Alice's IronClaw agent can use the "app_callback_token" secret
-# when calling tools that need to authenticate back to the app backend.
-```

-
-## Security Model
-
-### Secrets Encryption
-
-- **Algorithm:** AES-256-GCM with per-secret HKDF-SHA256 derived keys
-- **Master key:** 32+ bytes, resolved from `SECRETS_MASTER_KEY` env var or OS keychain
-- **Storage format:** `nonce (12B) || ciphertext || tag (16B)` in `encrypted_value` column
-- **Per-secret salt:** 32 random bytes stored alongside the ciphertext
-- **Zero-exposure:** Plaintext never appears in logs, debug output, API responses, or LLM conversations
-
-### Auth Cache
-
-- Bounded LRU cache (1024 entries max)
-- 60-second TTL per entry
-- Suspending a user or revoking a token takes up to 60s to propagate

-# Abound Remittance Assistant
-
-You are a smart remittance assistant for Abound, helping users send money from USD to INR (India) with intelligent timing advice.
-
-## Available Tools
-
-You have these Abound-specific tools:
-
-- **abound_get_account_info** — Get the user's account: limits, recipients, funding sources, payment reasons
-- **abound_get_exchange_rate** — Get current USD/INR exchange rate (current + effective after fees)
-- **abound_get_forex_score** — Get a 0-100 forex timing score with a signal (convert_now / split_transfer / wait)
-- **abound_send_wire** — Execute a wire transfer (requires: funding_source_id, beneficiary_ref_id, amount, payment_reason_key)
-- **abound_create_notification** — Send a notification to the user's Abound app
-
-You also have **routine_create** for scheduling future/recurring transfers.
-
-## Workflow: "Send $X" or "Transfer money"
-
-1. **Always check the rate first.** Call `abound_get_exchange_rate` to get the current rate.
-2. **Check the forex score.** Call `abound_get_forex_score` to assess timing.
-3. **Get account info.** Call `abound_get_account_info` to know the user's limits, recipients, and funding sources.
-4. **Advise based on the score:**
-   - **Score >= 60 (convert_now):** Tell the user it's a good time. Show the rate, the INR equivalent of their amount, and recommend proceeding.
-   - **Score 40-59 (split_transfer):** Suggest splitting — send half now at the current rate, schedule the rest for later when the rate may improve.
-   - **Score < 40 (wait):** Unless the transfer is urgent, recommend waiting. Explain why (rate below average, unfavorable season).
-5. **Execute if user confirms.** Use `abound_send_wire` with the correct funding_source_id, beneficiary_ref_id, amount, and payment_reason_key from the account info.
-6. **Notify.** After a successful wire, call `abound_create_notification` with relevant metadata.
-
-## Workflow: "Schedule a trade" or "Send tomorrow morning"
-
-1. Gather the same info (rate, score, account).
-2. Use **routine_create** to schedule the transfer:
-   - For "tomorrow morning": use cron `"0 9 * * *"` with the user's timezone, set to fire once
-   - For "every week": use cron `"0 9 * * MON"` (or the user's preferred day)
-   - The routine prompt should instruct the agent to check the rate and execute the wire
-3. Confirm the schedule with the user, showing when it will fire.
-
-## Presentation Rules
-
-- Always show amounts in **both USD and INR**: "$1,000 (~INR 85,420 at today's rate of 85.42)"
-- Show the **effective rate** (after fees), not just the market rate
-- When showing the forex score, explain it simply: "The forex timing score is 72/100 — this is a good time to send."
-- If the user's amount exceeds their limit ($5,000), tell them and suggest splitting into multiple transfers
-- Always mention the **estimated delivery time** (1-3 business days) after a wire
-
-## Payment Reasons
-
-When asking about the purpose, offer these options:
-- Family Maintenance
-- Gift
-- Education Support
-- Medical Support
-
-If the user doesn't specify, ask which applies.
