docs(skills): release-and-publish is stale against mcp-ts-core — version reads ahead but content is behind

Description

skills/release-and-publish/SKILL.md in this repo declares metadata.version: "2.9", while the current @cyanheads/mcp-ts-core copy of the same skill (node_modules/@cyanheads/mcp-ts-core/skills/release-and-publish/SKILL.md) is at "1.11". Because the local version string reads numerically ahead of the framework's, a version-gated resync treats it as an intentional local override and leaves it untouched — but a content diff shows the local copy is missing real upstream guid

bug(ia_get_snapshot): Wayback 404 on exact-timestamp direct path doesn't map to no_snapshot_available contract

When ia_get_snapshot is called with an exact 14-digit timestamp (e.g. "20200601000000"), the handler skips the Availability API and calls fetchContent directly. If the Wayback Machine returns a 404 for that URL/timestamp combination (no capture at that exact timestamp), the raw FetchHttpError propagates without being mapped to the declared no_snapshot_available contract entry. The result: data.reason is null and the error text is the generic fetch failure message, not the actionabl

ux(ia_search_items): empty-result notice lives only in structuredContent, not in content[]

ia_search_items uses ctx.enrich.notice() to surface actionable guidance when the query returns zero results. The notice is correctly placed in structuredContent.notice — visible to Claude Code and API clients reading structured output — but the format() function only renders the result-count line, leaving content[] with no guidance text.

Clients that only consume content[] (Claude Desktop, stdio integrations) see nothing helpful when a search returns zero results.

ux(ia_get_snapshot): resolved_status is hardcoded '200' for exact-timestamp direct path

Server version

0.1.1

mcp-ts-core version

^0.9.21

Description

In ia-get-snapshot.tool.ts, when the caller passes an exact 14-digit timestamp, ia_get_snapshot builds the replay URL directly and skips the Availability API check. The resolved_status field is hardcoded as '200' in this path:

if (isExactTimestamp) {
  snapshotUrl = svc.buildReplayUrl(input.timestamp.trim(), input.url);
  resolvedTimestamp = input.timestamp.trim();
  resolvedStatus = '200'; // status wil

### bug(ia_get_item): dark/restricted items return empty metadata instead of an error

### Transport

### Description

The Internet Archive Metadata API returns `HTTP 200` with a non-empty response body for dark (restricted/removed) items, but the body contains only server routing fields (`created`, `d1`, `d2`, `dir`, `is_dark`, etc.) — no `metadata` key and no `files` array.

The current check in `archive-metadata-service.ts` only throws `item_not_found` when the respo

### Description

`ia_find_snapshots` with `mode=closest` always returns `no_snapshot_available`, even for well-archived URLs like `example.com`. The same bug breaks `ia_get_snapshot` when a non-exact (< 14-digit) timestamp is passed, since both code paths call `WaybackService.findClosest()`.

Root cause: the SSRF guard in `wayback-service.ts` validates that the Availabi

### docs: SECURITY.md and CONTRIBUTING.md ship unresolved template author-comments

### Description

`.github/SECURITY.md` and `.github/CONTRIBUTING.md` were scaffolded from templates that include HTML comments meant to guide the maintainer before publishing (e.g. whether GitHub private vulnerability reporting is enabled, whether to commit to a response-time window, whether PRs are accepted). The placeholder tokens were filled in correctly, but the guidance comments were left in verbatim and are now committed to the public repo:

### feat(config): default MCP_SESSION_MODE to stateless across env, Docker, and src

`Dockerfile` sets `ENV MCP_SESSION_MODE="stateless"`, but `.env.example` carries a commented `# MCP_SESSION_MODE=stateful`, whose comment documents the value set as `stateful | stateless (default: stateful)`. The container and the same code run via `bunx`, `npm start`, or from source therefore resolve to different session modes — stateless in Docker, stateful everywhere else, since the framework schema defaults to `auto` and `auto` resolves to `stateful`.

### feat(ia_get_item): cap or paginate the file manifest — large items bloat both response surfaces

### Use case

`ia_get_item` returns the complete file manifest with no cap, and `format()` renders every file into `content[]`. Routine multi-file items make this heavy: a single LibriVox audiobook lookup — `adventures_holmes` (126 files) — produces ~24 KB of `content[]` text plus ~30 KB of `structuredContent` (~53 KB / ~14K tokens) for one call; `LibrivoxM4bCollectionAudiobooksMain` has 285 files. The manifest dominates the response and is duplicated across both surfaces, even though a caller u

### docs(ia_get_item): example identifier pg1342 is now a dark item — advertised resource example errors

### Description

`pg1342` ("Pride and Prejudice") is the canonical example identifier across the metadata surface: the descriptions of `ia_get_item` and `ia_get_text`, the `ia://item/{identifier}` resource's `params` description, and — functionally — the resource's `list()`, which advertises `ia://item/pg1342` as *"Example: Pride and Prejudice (pg1342)"*.

That item is now **dark**: `https://archive.org/metadata/pg1342` returns routing fields with `is_dark: true` and no metadata or files. So the
