docs(subsystems): open core.md on agent creation/ownership and the Agent contract; enforce a complete folder index

Browse Source 
core.md claimed to be the packages/core reference but opened on repo-wide type patterns and never documented the ownership vocabulary: AgentHandle, CreateAgentOptions, ResumeAgentOptions, and AgentFactory were TYPE_LINK_EXEMPTIONS pointing at a package README, invisible to the folder that calls itself the type reference. The page now reads spine map -> creation and ownership (AgentHandle pasted; the options and factory summarized with links into the generated registry section) -> the Agent handle (AgentStatus, AgentOptions, SteeringOutcome, SteeringReceipt, and SettleReason now pasted; the one settlement prose wall split by topic; delivery vocabulary ordered as a message travels) -> initiator -> interception -> a Sessions summary -> the ToolDefinition pointer -> an explicitly framed repo-wide patterns tail (the ...Map pattern, branded ids). The duplicate SessionEvent paste is gone -- session.md owns it and LINK_MAP follows -- the four ownership types moved from TYPE_LINK_EXEMPTIONS into LINK_MAP -> core.md, and three dead LINK_MAP entries (ContinuationDecision, ContinuationStop, HookContext) no longer name types absent from the source tree. The "what this page owns" meta-section folds into the intro.

The subsystems README index silently lost tasks.md and session-reference.md on both language sides during a base absorption; the rows are restored and scripts/project-doc-site.spec.ts now fails when any page misses either side of the index (proven red on a removed row). tools.md links ToolSchema to its llm-streaming.md declaration instead of calling it core; subagent.md links AgentHandle and CreateAgentOptions.seed to the new section. A new Agent Note records the package-anchored page-scoping decision; the 2026-06-20 catalog note marks its spine-vs-seam rule superseded as the page-scoping rule while keeping the type-equiv mechanism current, and docs/AGENTS.md cites the new note.

溯源与形态是相互独立的两根轴。`kind` 回答「由谁产生」；生产方可选混入的 `form` 回答「这是何种形态的信息」，因此多个生产方可以共用一种呈现，一个生产方在一次会话中也可以发出多种形态。该词汇表是语义的，逐个取值增长；未声明或无法识别的取值是有文档的默认，按不透明内容呈现：

/**
* What SHAPE of information a producer-supplied context carries, declared by
* the producer beside its provenance.
*
* `MessageSource.kind` answers *who produced this*; `form` answers *what kind
* of thing it is*, and the two axes are deliberately independent — several
* producers share one form (three snapshot producers today), and one producer
* may emit more than one form over a session.
*
* The vocabulary is SEMANTIC, never visual: a value states that the content is
* a file's instructions or a catalog of available items, and a consumer decides
* what that looks like. Colors, icons, ordering, and collapse defaults are the
* consumer's business and must not enter this union. It grows one value at a
* time as producers gain the structured fields their form needs; an absent or
* unknown value is the documented default, presented as opaque content.
