Tianyi Cui d488330ba4 fix(rebase): migrate the replayed E2B branch onto the rebased parent
The linear replay carried old-lineage content over parent-owned files;
this checkpoint restores them and adapts the branch to the parent's
post-rebase seam:

- restore all pty/lsp/subprocess/code-runtime surfaces to the parent's
  exact content (this branch claims none of them) and drop the net-zero
  code-runtime-e2b/pty-e2b/lsp-e2b residue and its registrations
- widen serializeRemoteEnvironment to the seam's NodeJS.ProcessEnv
  tombstone contract: an explicit undefined removes an ambient entry
- migrate the two E2B fixture Agent stubs to the Inbox-model interface
  and Session.create
- re-apply the branch's gen-doc-graphs roles, THIRD_PARTY_NOTICES e2b
  row, and packages/README group row (trimmed to the doc budget);
  regenerate catalogs and re-record bilingual pairings

lsp/ - LSP capability family

English | 中文

The language-server capability seam: an abstract LSP interface, a generic stdio provider, and the model-facing lsp tool. All product packages.

Package Role ctx key
lsp/ Abstract LSP seam (provider registry by branded id + extension mapping, per-query selection, vocabulary, LspError) ctx.lsp
lsp-local/ Generic multi-server stdio backend over ctx.fs and ctx.subprocess (JSON-RPC, transient-open queries) (registers providers on ctx.lsp)
tool-lsp/ Model-facing lsp tool (four operations, one-based UTF-16 cursor coordinates) (registers on ctx.tools)

The interface lives at lsp/lsp/. The seam exposes exactly four semantic operations — goToDefinition, findReferences, goToImplementation, hover — and no generic JSON-RPC escape hatch, so a provider swap does not change how the model asks for navigation and no protocol payload or unreviewed mutation reaches the model contract. Providers register capabilities, not tools; tool-lsp is the only owner of the model-facing name, schema, prompt guidance, and presentation.

See the LSP capability seam Agent Note for the design rationale, including why documents open transiently per query, why the stdio host consumes the shared filesystem/subprocess execution world, and why extension ownership is exclusive within one runtime.
