feat(settings): Agents settings hub + dedicated agent editor

[senamakel]

Summary

• New Settings → Agents hub that groups Manage agents, Persona, Agent autonomy, and Agent OS access under one section page (previously scattered across the top-level menu / AI section).
• Replaced the in-panel agent editor modal with a dedicated full-page editor (/settings/agents/new, /settings/agents/edit/:id): name-as-title, description textarea, model dropdown (route hints / tiers + custom-id escape hatch), and a searchable tools picker modal with chip-style selection and per-tool descriptions.
• Built-in agents are now non-editable — only custom agents expose Edit; built-ins keep enable/disable + reset. Deep-linking to edit a built-in shows a read-only notice.
• New openhuman.agent_registry_available_tools RPC backs the tools picker, returning the full built-in tool catalog (name + description).
• Fixed AgentAccessPanel dark mode (it used undefined ink/line Tailwind tokens that never adapted).
• Housekeeping: removed whatsapp_data_* tools from the orchestrator's direct tool list (still registered + assignable to custom agents via the catalog).

Problem

• Agent-related settings were spread across the top-level Settings menu and the AI section, with no single home. The agent editor was a cramped modal of plain text inputs — model was free-text (with a misleading hint:fast placeholder that isn't a valid hint) and tools were a newline-joined textarea with no discoverability.
• AgentAccessPanel rendered with non-existent Tailwind color tokens, so its text/borders didn't adapt to dark mode.
• The orchestrator carried WhatsApp local-data tools directly in its curated tool list.

Solution

• Added an agents-settings section route + breadcrumbs in useSettingsNavigation, and a single Agents entry on the Settings home.
• Built AgentEditorPage + ToolsPickerModal; model options mirror the Rust tier/hint constants, empty = inherit.
• Added agent_registry_available_tools (ops/rpc/schema + AgentToolInfo type) built from the wildcard tools_agent so the picker lists the complete assignable catalog rather than the orchestrator's curated named subset.
• Removed the WhatsApp tools from orchestrator/agent.toml; they remain registered and selectable for custom agents.
• Replaced AgentAccessPanel's undefined tokens with the stone/neutral palette + dark: variants, matching the canonical AutonomyPanel.

Submission Checklist

• Tests added or updated (happy path + at least one failure / edge case) per Testing Strategy
• Diff coverage ≥ 80% — added Vitest (AgentsPanel, AgentEditorPage) + Rust json_rpc_e2e and schema unit tests covering the new/changed lines; happy + failure/edge paths.
• N/A: settings-panel reorganization + editor UI; no capability-catalog feature ID was added/removed/renamed in the coverage matrix.
• N/A: no coverage-matrix feature IDs affected by this change.
• No new external network dependencies introduced (mock backend used per Testing Strategy)
• N/A: does not touch release-cut smoke surfaces.
• N/A: no linked issue.

Impact

• Desktop UI (React/Tauri): Settings navigation reorg + new editor page. Frontend changes hot-reload; the new RPC requires a core rebuild.
• Core (Rust): one additive RPC (agent_registry_available_tools); orchestrator tool list shrinks by 3 WhatsApp tools (still registered globally — no capability removed).
• No migrations, no security/perf implications. i18n keys added across all locale chunks (English placeholders for non-English).

Validation Run

• pnpm --filter openhuman-app format:check (ran prettier --write on changed files)
• pnpm typecheck
• Focused tests: AgentsPanel (5), AgentEditorPage (4) Vitest; json_rpc_agent_registry_manages_defaults_and_custom_agents + agent_registry lib (80) + agent_retrieval_e2e (4)
• Rust fmt/check (if changed): cargo fmt --check + cargo check --lib
• N/A: Tauri shell (app/src-tauri) unchanged.

Validation Blocked

• command: N/A
• error: N/A
• impact: N/A

Behavior Changes

• Intended behavior change: Agents settings consolidated; built-ins read-only; dedicated agent editor with tools picker.
• User-visible effect: New Settings → Agents hub + full-page agent editor; built-in agents can be toggled/reset but not edited.

Parity Contract

• Legacy behavior preserved: enable/disable + reset of built-ins, custom create/update/delete unchanged; existing agent_registry RPCs untouched.
• Guard/fallback/dispatch parity checks: orchestrator-disable guard intact; available_tools is additive.
