chore(release): 0.3.0

Adds external key custody ([#33]) — a config-held reference to a key kept in a
secret manager, resolved per command. Contains one behaviour change, so the
next publish must not ship as a patch: wallet init no longer silently replaces
a configured wallet.

Atomic bump: package version, both skill frontmatters, version pins in skill
examples, and the changelog Unreleased retitle — CI pins them together.

+## [0.3.0] — 2026-08-05
+
+External key custody. `foc-cli` can now hold a *reference* to a key kept in a secret manager instead of the key itself, closing the gap that left MCP and CI with no option but a key in the config file. Contains one behaviour change to `wallet init` (hence the minor bump).
+
+### Added
+
+- `wallet init --keyRef <provider>:<reference>` — a third custody mode alongside a raw key and a Foundry keystore. The config stores only the pointer; the key is fetched into memory per command and never written to disk. Nothing prompts, so unlike keystore mode this works under the MCP server and CI. `--keyProject` scopes the reference; omitted, the provider picks its own default. `clawdi` is the first provider. ([#33])
+- `wallet balance` now reports `keySource` (`keyRef` / `keystore` / `privateKey`), so a vault-backed setup is verifiable at a glance — the address proves which key signed, this proves where it came from. Never the key. ([#33])
+- Preflight checks on every wallet-touching command: `WALLET_NOT_CONFIGURED` and `KEY_REF_PROVIDER_MISSING` now arrive as typed errors with actionable CTAs, instead of escaping as an untyped throw from inside key resolution. The preflight does not resolve the key — that needs an authenticated provider and a round trip, and belongs at use time. ([#33])
+- `wallet init --force`. ([#33])
+
+### Changed
+
+- **`wallet init` no longer silently replaces a configured wallet.** An explicit method used to overwrite whatever was configured, discarding a key that may have been the only copy. It now names what would be lost — the derived address for a private key, the path for a keystore, the reference for a key reference, never the key itself — and asks on a terminal, or fails with `WALLET_ALREADY_CONFIGURED` and a `--force` CTA in agent mode. Re-running the *same* method with the same value replaces nothing and is never blocked. Automation that re-runs `wallet init --auto` expecting a fresh key must now pass `--force`. ([#33])
+- Call-to-action guidance only offers a key-reference method when that provider's CLI is actually installed on the machine — suggesting a tool the caller does not have is a dead end. The reference docs still describe every provider. ([#33])
+
+### Documentation
+
+- `references/key-injection.md` — identification table first (most of the time the answer is "already set up, run normally"), then setup, providers, what the mode does and does not protect, and the error catalog. ([#33])
+- `references/integrations/clawdi-vault.md` — the Clawdi recipe, including the per-project scoping that most often bites. ([#33])
+- `references/keystore-setup.md` now points at the key-reference mode as the automation-safe alternative it previously had no answer for. ([#33])
+

Reach for this whenever the user wants to actually run or execute an FOC/Synapse storage action, even if they don't name the tool.

The CLI is free and defaults to the free Calibration testnet; storing data on mainnet (--chain 314) spends real USDFC. For looking up documentation or SDK reference (rather than running a command), use the foc-docs skill instead.

 ## Security & Agent Safety
 
 - **Money moves are real.** `wallet deposit`, `wallet withdraw`, `upload`, and `dataset create` spend or commit USDFC through onchain transactions that cannot be reversed once confirmed. The default chain is Calibration testnet (faucet-funded, no real value); anything run with `--chain 314` uses mainnet and real funds. Agents must obtain explicit human confirmation before any mainnet or fund-moving operation, never chain them autonomously, and must show the `wallet costs` estimate first.

For reproducible, supply-chain-safe scripts and CI, pin the release you have vetted, e.g. `npx foc-cli@0.2.0` (example version; update the pin as releases ship). The official package is [`foc-cli` on npm](https://www.npmjs.com/package/foc-cli), published from [FIL-Builders/foc-cli](https://github.com/FIL-Builders/foc-cli).

 - **Keys stay local.** See "Private key safety" under Setup — nothing in this skill ever requires sharing, printing, or transmitting a private key.

 ## Security Notes
 
 - **Read-only and restricted to the docs host.** `foc-cli docs` fetches pages only from `docs.filecoin.cloud`: `--url` accepts a full docs URL or a docs path (e.g. `developer-guides/synapse.md`) and rejects any other host with `INVALID_DOCS_URL` before fetching. Redirects are not followed, so the restriction holds end-to-end. It requires no wallet, reads no keys, and cannot move funds — safe to run without confirmation.
