Bump GRAPH_VERSION so the tree-sitter fix reaches existing caches

[nedonatelli]

Defect in #48, found while verifying #48.

What happened

#48 made tree-sitter load in a packaged install. I did not bump
GRAPH_VERSION, so nothing re-parsed and the fix was invisible to anyone
with an existing graph — including the install used to verify it.

Reconciliation skips a file whose content hash is unchanged:

if (restored && this.graph.getFileHash(relativePath) === hash) return;

and restore() accepts any cache whose version matches. Swapping the extractor
changes no file's content, so an upgraded install restores its regex-built graph
at v5, matches every hash, re-parses nothing, and keeps serving symbols from the
parser that was just replaced.

Measured, after installing the fixed build and reloading

The method kind is the unambiguous tell — the regex analyzer emits none at all:

kind	tree-sitter	regex	live cache
method	1487	0	absent
function	2275	4468	4432
class	201	214	214
enum	9	19	19
interface	611	639	639

Everything matched regex. Meanwhile createTreeSitterAnalyzer pointed at the
installed extension's grammars loads fine — 28 extensions, and it correctly
emits m:method. So the module, the grammars and the loader were all working;
the graph simply was never rebuilt.

Why this is the same lesson twice

v4 bumped for variable symbols and v5 for generators, both with the reasoning
written into the comment: the affected files do not change, reconciliation is by
content hash, so without a bump the cache serves stale extraction forever.

Replacing the entire extractor is a strictly larger invalidation than either,
and it is the one I missed.

For anyone testing locally

Deleting .sidecar/cache/symbol-graph.json and reloading achieves the same
thing without this change — but that is not available to users upgrading, which
is what the version field is for.
