Backend: `links::resolve_id` now checks for an exact live node id before
alias/title, so a canonical `[[NODEID]]` link resolves to its node and
can't be shadowed by a like-named node. Legacy `[[Name]]` links still
resolve by name (until the migration), so this is additive.
heph.nvim: `link.insert` (bound to insert-mode `[[` and `:Heph link`)
searches via the `search` RPC and inserts `[[NODEID]]`, with a "+ Create
new doc" entry; `<CR>` follow resolves the id directly. e2e covers
search→insert→materialize and the create path.
Remaining (§8.4): read-expansion/conceal display + the one-time
[[Title]]→[[NODEID]] migration (then retire name-resolution + the hack).

A buffer-local syntax match (`HephHashtag`, italic, `default`-overridable)
highlights whitespace-prefixed #hashtags so they're visually obvious —
mirroring the save-time tag detection (a `# heading` doesn't match).
Attached alongside the <CR> link follow. Syntax match is the right-sized
tool here (treesitter has no hashtag node; extmark conceal is reserved
for the upcoming [[link]] display layer). e2e asserts the italic hl group.

Pressing <CR> on a [[wiki-link]] whose target doesn't exist now creates a doc
with that title and opens it (the zettelkasten gesture), and materializes the
source's backlink: if the source has unsaved edits, saving re-extracts and
links it (and persists the edits); otherwise the wiki link is added directly
(a no-op re-save wouldn't re-extract). Adds :Heph doc <title> to create a
standalone wiki entry. e2e covers both the saved-source and just-typed-source
paths.

The primary surface begins (tech-spec §8): a Neovim plugin that is a thin
client of the local hephd over its unix-socket JSON-RPC.
- node.resolve {title} → Node|null (heph-core Store + dispatch): exact,
owner-scoped, non-tombstoned alias-then-title match — the same mapping that
materializes wiki links, so follow-link jumps to the node the stored link
points at (never fuzzy search). Unit + rpc_socket integration tests.
- heph.nvim/: vim.uv unix-socket JSON-RPC client (blocking call via vim.wait,
id-demuxed, partial-line buffered, luanil so JSON null → Lua nil; isolated
Sessions for tests). Buffer-backed nodes (heph://node/<id>, acwrite;
BufReadCmd→node.get / BufWriteCmd→node.update, whole-buffer body round-trips
exactly through the CRDT). [[wiki-link]] follow on <CR>. Daily journal.
:Heph command surface + completion.
- Headless e2e (§9): a self-contained busted-style runner (tests/e2e/runner.lua)
— no external plugins, no network, deterministic CI exit codes. Specs: journal
round-trip, follow-link (+ unresolved no-op), link-two-docs/backlink.
`make -C heph.nvim test` builds hephd and runs it.
Docs: heph-nvim reference card, §14 tracker (11a done; 11b/11c/11d queued),
changelog fragment.
