Eru.Tool 0.9.0

This package has no dependencies.

`eru source add --scan` detects OKF bundles (any `index.md` with `okf_version`; a root marker covers nested ones) and falls back to the `knowledge/` convention. **Breaking:** without `--scan`, `eru source add` no longer auto-detects the `knowledge/` bundle; register bundles with `eru source bundle add`
OKF bundle discovery (and so `eru site generate`) now indexes only concept files that have a non-empty `type` frontmatter; untyped markdown is skipped
`eru okf verify <file>` records a `{ by, at }` confirmation in a concept file's `verified` list (`--by` defaults to `human:<git user.email>`, `--at` to now); `eru okf fix` now strips a malformed `verified` (placeholders like `unknown`/`false`, entries missing `by`/`at`), keeping valid entries; `eru okf validate` warns on placeholder `verified` values and `by: unknown`, pointing at `fix` and `verify`
OKF v0.2 alignment: `eru okf init`/`fix` write `okf_version: "0.2"`; `eru okf validate` reports non-fatal v0.2 shape warnings (`generated`, `verified`, `stale_after`, `status`, `sources`, legacy `timestamp`, `log.md` order); eru reads `sources` and falls back to a legacy `timestamp` when `generated` is absent; the ingestor agent template now writes spec-shaped `generated`/`sources` and omits `verified` until a human reviews; `eru inbox send` quotes `resource` in its frontmatter
`eru okf init <path>` creates missing `index.md` files (root with `okf_version`, plus a catalog table per folder), never overwriting; `eru okf fix <path>` repairs a tree so `eru okf validate` passes (index frontmatter, missing concept frontmatter/`type`, non-ISO `log.md` date headings, missing indexes). Both write by default; `--dry-run` previews, `--default-type` sets the type for untyped concepts
`eru source bundle add` warns when a bundle is auto-detected as `manifest` but has no `.eru/manifest.json`, listing the ways to fix it (add `okf_version` to `index.md`, pass `--kind okf`, or create a manifest); `eru source add` does the same for a detected `KNOWLEDGE/` bundle
`eru okf validate`: the bundle-root `index.md` frontmatter message now explains that it should contain only `okf_version`, which is what makes eru detect an OKF bundle
`README.md` and dot-directories (`.github`, `.claude`, `.agents`, …) are no longer treated as OKF concepts: they are skipped by `eru okf validate` and OKF bundle discovery
`siteIgnorePatterns` now defaults to `index.md`, `log.md` and `README.md` (configs with an explicit value are unchanged)
`okfIgnorePatterns` setting (default `apm_modules/**`, `inbox/**`, `node_modules/**`) to skip paths during OKF bundle discovery and `eru okf validate`
`eru version` command prints the version and the git commit it was built from
Added description field to the manifest
Remote git inboxes: `eru inbox add <name> <git-url> [--branch]` registers a repo as an inbox and `eru inbox send` clones it shallowly, commits the item and pushes (via FsForge); remote inboxes are send-only
Added `eru site serve` command to serve the generated static site locally with live reload on changes to the cache
`eru okf validate <path>` command to check a directory tree for OKF §11 conformance (parseable frontmatter with a non-empty `type`, valid `index.md`/`log.md` structure); never flags unknown types, unknown extra keys, broken cross-links, or missing optional fields
Generated site now surfaces OKF frontmatter: a trust-tier badge per file (`unverified`/`machine-confirmed`/`human-reviewed`, derived from `verified[].by`) and a new "Types" filter/browse page alongside the existing Sources and Tags
Added `SiteIgnorePattern` with default values of "index.md" and "log.md" to ignore OKF structure files when generating site pages
OKF bundle discovery on sources
`eru inbox` commands for handling inboxes/channels and sending to inboxes
`eru inbox process` command to run pending inbox items through their channel's configured ACP agent, archiving processed items; supports `--inbox`, `--channel`, `--item`, `--all`, `--dryrun`, and `--output`; `--debug` also reports per-item agent handshake timings (initialize/session-new/prompt)
`eru inbox watch` command to watch an inbox's raw directory and automatically run `inbox process` on new items, debounced and also polled on a configurable interval (`--interval`, default from config); supports `--dryrun` and `--debug`
`--agent-timeout` option on `eru inbox channel add` to bound how long an ACP agent call may run; the timeout is a liveness check (reset on any agent activity) rather than a fixed deadline
ACP agent output is streamed as it arrives instead of only being shown once the call completes
`eru inbox process` now falls back further when a channel has no `--agent-instructions` configured and `<inbox>/.agents/agents/ingestor.md` doesn't exist: it checks a tool-specific convention path derived from `--agent-command` (e.g. `.claude/agents/ingestor.md` for `claude`), and finally falls back to eru's own built-in curation instructions — so a channel's agent always receives some curation instructions
`--append <text|@file>` (repeatable) on `eru inbox process` and `eru inbox watch` adds text to the agent prompt after the resolved instructions and before the item; a leading `@` reads a file, `@@` is a literal `@`
Built-in ingestor instructions (`agents/ingestor.agent.md`) now produce a valid OKF bundle: folder `index.md` files get no frontmatter, the root `index.md` carries only `okf_version`, `README.md` is treated as outside the bundle, and the agent uses `eru okf init` for new folders and `eru okf validate`/`fix` as a final self-check
Built-in ingestor instructions (`agents/ingestor.agent.md`) no longer loop until `inbox/raw/` is empty; the agent processes only the items it is told to (by `eru`, a harness prompt, or a workflow) and asks if none are specified
Built-in ingestor instructions (`agents/ingestor.agent.md`) no longer include a commit step, so they stay neutral across environments; use `--append` to add commit/PR behaviour
`eru manifest verify` renamed to `eru manifest validate`; `verify` is kept as a backward-compatible alias
`eru add` gives a clearer error when passed a bare repo URL, suggesting `eru source add <url>` followed by `eru add <source>:<path>`
Unhandled exceptions now print a concise `eru: unexpected error: <message>` instead of a raw stack trace; pass `--debug` to see the full stack trace
OKF bundle discovery no longer fails when a source has no branch configured
Pinned the test runner via `global.json` (`Microsoft.Testing.Platform`) to fix `dotnet test` discovery
