Adds the URI-only store views the semantic-frontend producer arc
needs. The stores key by (server, uri); the producer only knows the
document, so `for_uri` scans by uri and picks the lowest *numeric*
server id deterministically (HashMap order is otherwise
nondeterministic; lowest id == oldest/primary attachment). Blending
multiple servers' styling on one buffer is a deferred open question.
Inlay-hint `for_uri` returns no server: Step 0 established inlay
positions are already pmacs byte offsets by the time they hit the
store (the absorb path's inbound_converted rewrites the
Position-shaped InlayHint.position), so the producer needs no
per-server encoding for them. Semantic tokens differ — start/length
stay UTF-16, hence the (server, response) tuple so the matching
LspManager::semantic_style_context can resolve encoding + legend.
Also repairs main: PR #28 (file-watch) inadvertently swept in the
uncommitted lsp.rs side of this work — SemanticStyleContext and
semantic_style_context, which call store.for_uri — without these
defining accessors, leaving main referencing an undefined method
(no method `for_uri`). This commit supplies the missing definitions,
so main compiles again.

Independent LSP feature (not part of the L1-L4 cross-file arc),
shipped in the same shape as every sibling: typed store + async
request + Lua surface + command + modeline summary, with the
inline renderer deferred as its own milestone.
- src/inlay_hint.rs: parse InlayHint[]|null — position, label
(string OR InlayHintLabelPart[] flattened), kind (type/
parameter), paddingLeft/Right, tooltip (string|MarkupContent).
Store keyed (server, uri). 5 unit tests.
- src/lsp.rs: inlay_hint_store + accessor, ResponseRoute::InlayHint
+ absorb, request_inlay_hint (range params), textDocument.
inlayHint client capability (no resolveSupport/refreshSupport —
full hints, on-demand re-query is the v1 model).
- src/lua_bindings.rs: _request_inlay_hint_raw,
pmacs.inlay_hint.{hints,clear}.
- pmacs_fake_lsp.rs: textDocument/inlayHint arm returning a
string-label type hint and a label-parts parameter hint.
- builtin/runtime/lsp.lua: pmacs.lsp.inlay_hints() requests over
the whole-buffer range, stores, modeline summary;
lsp.inlay-hints command + C-c i; scope header notes the inline
renderer is a later milestone.
- tests/m4_acceptance.rs: m4_16 drives the request via the Lua
surface, asserts both label shapes / kinds / padding parsed.
Deferred (scoping, not a regression): inline virtual-text
rendering. The VirtualCellOverlay model only overwrites existing
cells; rendering hints inline needs a column-inserting/reflowing
renderer — a rendering milestone, not an LSP task — staged like
the hover panel / references list. pmacs.inlay_hint is the data
surface a future render layer subscribes to.
Gates: lib 1279/0, m4 71/0, m8_1 10/0, m8_9 26/0, m8_10 19/0,
m9_1 18/0, m5_8 5/0, m11_5 (--features crdt) 2/0; fmt + clippy
clean.
