The @vault=<vault-name>:<key> prefix for webhook secret resolution shipped in #2163 (commit 4e94763) but has no user-facing documentation. Users discovering webhook configuration via the docs won't know they can reference vault-managed secrets alongside the existing @env= and @file= prefixes.

Proposed Solution

Add documentation covering:

@vault= syntax — @vault=<vault-name>:<key> resolves the secret from the named vault at serve startup
Supported prefixes summary — document all three secret resolution prefixes together (@env=, @file=, @vault=) so users can compare options
Example serve.yaml snippet — show a webhook block using @vault= with a configured vault backend
Vault backend transparency — note that any configured vault backend (local encryption, AWS Secrets Manager, etc.) works transparently with @vault=

Alternatives

Rely on users reading the commit history or PR description — not discoverable enough for a user-facing feature

dataOutputOverrides not applied during remote execution — ephemeral resources GC'd before override takes effect

extension rm also deletes the lockfile entry, and install on an empty lockfile is a silent success — rm/install is not a round trip

Retyping a model instance strands catalog rows no command can reclaim — prune matches on model_id, delete resolves the current type (follow-up to #1009)

knowledge-base retrieve persists query output into the state resource, with lifetime infinite and the query text in the instance name

Method-name collision between a base model type and an extending extension silently drops the whole extension file — no error, doctor reports pass
