* feat: add libSQL/Turso database backend with full feature parity
Introduce a Database trait abstraction (~60 async methods) enabling
compile-time backend selection between PostgreSQL and libSQL/Turso.
Convert all modules from concrete Store to Arc<dyn Database>, add
LibSqlSecretsStore and LibSqlWasmToolStore implementations, wire
libsql stores throughout CLI and main entry points, and make the
setup wizard backend-agnostic.
Key changes:
- src/db/: Database trait, PostgresDatabase adapter, LibSqlBackend
with native SQLite-dialect SQL, and idempotent migration system
- src/secrets/store.rs: LibSqlSecretsStore (all 8 trait methods)
- src/tools/wasm/storage.rs: LibSqlWasmToolStore (all 7 trait methods)
- src/main.rs, cli/tool.rs, cli/mcp.rs: backend-conditional wiring
- src/setup/channels.rs: SecretsContext uses Arc<dyn SecretsStore>
- Feature-gate postgres-only tests and examples

* feat: enable onboarding wizard for libSQL builds
Refactor the setup wizard to work with both postgres and libsql feature
flags. Previously the wizard was gated behind #[cfg(feature = "postgres")]
only, so libsql-only builds would print an error on `ironclaw onboard`.
- Add libsql fields to Settings (database_backend, libsql_path, libsql_url)
- Split wizard database/migration/secrets methods into feature-gated variants
- Add step_database_libsql() with local path and Turso remote replica prompts
- Update setup/mod.rs and main.rs feature gates to any(postgres, libsql)
- Extend check_onboard_needed() to detect libsql database presence

* fix: address PR review feedback for libSQL backend
- P0: Switch libsql_backend to connection-per-operation pattern to fix
shared Connection concurrency issue across tokio tasks
- P0: Wrap secrets store INSERT+SELECT in transaction to fix TOCTOU race
- P0: Document encryption-at-rest limitations and json_patch divergence
- P1: Fix get_opt_text removing .filter(|s| !s.is_empty()) that conflated
empty strings with NULL
- P1: Replace datetime('now') with fmt_ts(&Utc::now()) for consistent
RFC 3339 timestamps across all queries
- P2: Use explicit _rowid column in FTS5 triggers and joins for stability
across VACUUM operations
- P2: Add tracing::warn when embedding provided but vector search disabled
in hybrid_search
- Extract shared connect_from_config() helper to deduplicate DB connection
logic across main.rs, cli/config.rs, and cli/mcp.rs

* fix: add missing JobContext fields and resolve fmt/clippy warnings
Add total_tokens_used and max_tokens fields to JobContext in
libsql_backend.rs, apply cargo fmt, and fix clippy warnings.

* fix: review fixes for libSQL backend (shared connections, panics, indexes)
- Replace .expect() with proper error propagation in 3 call sites
- Share Arc<Database> between backend and stores instead of single Connection
- Add connect-per-operation pattern to LibSqlSecretsStore and LibSqlWasmToolStore
- Wrap store() INSERT + SELECT-back in a transaction
- Add ~22 missing indexes for parity with PostgreSQL schema
- Add 18 leak_detection_patterns seed rows matching PostgreSQL V2 migration
- Fix super:: import to use crate:: style
- Gate mask_password_in_url behind #[cfg(feature = "postgres")]
- Rewrite secrets store init with or_else chain for runtime backend selection

* fix: Resolve clippy lints (collapsible_if, too_many_arguments)
Collapse nested if blocks into let_chains to satisfy clippy's
collapsible_if lint (CI uses -D warnings). Suppress too_many_arguments
on libsql_row_to_tool_at since refactoring the positional index
pattern would be a larger change.

Extends the WASM sandbox with HTTP API capabilities, secrets management,
tool aliasing, and leak detection. Key security principle: WASM never
sees credentials, injection happens at host boundary.
New modules:
- secrets: AES-256-GCM encrypted storage with HKDF key derivation
- leak_detector: Aho-Corasick + regex pattern matching for secret exfiltration
- capabilities: Extended capability system (HTTP, ToolInvoke, Secrets)
- allowlist: HTTP endpoint validation with glob patterns
- credential_injector: Host-boundary credential injection
- rate_limiter: Sliding window per-tool rate limiting
- storage: WASM binary storage with BLAKE3 integrity verification
Leak detection happens at two points:
1. Before HTTP request (prevents exfiltration via URL/headers/body)
2. After response (prevents exposure in outputs returned to WASM)
