* feat(secrets): one-command token rotation + actionable startup errors for all secret sources
When a Bitwarden machine-account token expired, users saw a raw Rust
error dump (invalid_client + Location: + backtrace hints) and the only
fix was manually editing .env or re-running the whole setup wizard.
- New `hermes secrets bitwarden token` / `hermes secrets onepassword
token`: paste a new token (masked prompt or flag), the command probes
the backend BEFORE persisting — a rejected token changes nothing; a
good one is written to .env and the fetch caches are cleared.
- New optional SecretSource.remediation(kind, cfg) hook: startup
warnings now print a '→ Run `hermes secrets <name> token`…' fix-it
line after any fetch error, for bundled AND plugin sources (generic
per-ErrorKind defaults in the ABC).
- bws stderr is summarized to its cause line (Location:/backtrace noise
dropped) and invalid_client/invalid_grant/400 identity rejects are
now classified AUTH_FAILED (was INTERNAL) with a plain-English
explanation naming the token env var.
- op whoami probe accepts a candidate token so rotation validates the
NEW credential, not the ambient one.
Additive hook with defaults — no SECRET_SOURCE_API_VERSION bump.
* docs: fix MDX parse error in secret-source-plugin hook table
Escaped backticks around a <name> placeholder made MDX parse it as an
unclosed JSX tag, breaking the docs-site build. Use a plain code span
instead.
* docs(secrets): secret-source plugin developer guide + sidebar registration for 1Password page
- New developer-guide/secret-source-plugin.md: SecretSource contract
(never raises/prompts, fetch-only, timeout budget), framework-vs-plugin
ownership table, mapped-vs-bulk shape guidance, run_secret_cli()
subprocess-safety, registration + timing note, conformance kit usage,
ErrorKind reference.
- Register user-guide/secrets/onepassword in the sidebar (page shipped
in #59498 but was not listed, so it was unreachable from nav).
- Cross-link the user-guide plugin section to the new dev guide.
* docs: group all plugin guides under a Plugins subcategory in Extending
- Move guides/build-a-hermes-plugin.md -> developer-guide/plugins/index.md
(both locales) and make it the category landing page (slug pinned to
/developer-guide/plugins).
- New sidebar subcategory Developer Guide > Extending > Plugins holding
the general guide + all 8 provider-plugin docs (llm-access, memory,
context-engine, secret-source, model, image-gen, video-gen, web-search);
provider-doc URLs unchanged.
- Client redirect /guides/build-a-hermes-plugin -> /developer-guide/plugins.
- Update 30 cross-links across both locales.
