* feat(python): add bulk/projected accessors to avoid N+1 reconstruction

Add set-at-a-time, field-projected reads to the Python facade so callers can
enumerate the application in one round-trip instead of paying the per-entity
reconstruction get_all_methods_in_application() does (tens of thousands of Bolt
round-trips on large apps via the Neo4j backend).

New `PyCallableOverview` projection model and three accessors on the
PythonAnalysisBackend ABC, both backends, and the facade:

- get_callables_overview() -> List[PyCallableOverview]: every callable
  (methods, module-level and nested functions) as a lightweight projection.
- get_method_bodies(signatures) -> Dict[str, str]: batch source-body fetch.
- get_decorated_callables(markers) -> List[PyCallableOverview]: overviews
  filtered by decorator (fills the get_methods_with_decorators gap).

The in-process and Neo4j backends enumerate the same callable set (a "method"
is one a class declares directly, mirroring PY_HAS_METHOD). Offline unit tests
cover the in-process walk; the Neo4j test module asserts byte-for-byte parity
against it when a server is reachable.

* perf(python): reuse one Neo4j read session instead of one per query

PyNeo4jBackend._run opened a fresh driver session on every call, so the N+1
reconstruction fan-out (get_symbol_table / get_all_methods_in_application) paid
session-acquisition overhead on each of its tens of thousands of queries. Reuse
a single lazily-opened session for the backend's lifetime, dropping it on error
so the next call reopens cleanly. Closed in close().

* chore: sync uv.lock with codeanalyzer-typescript 0.4.3

The lockfile still pinned codeanalyzer-typescript 0.4.0 while pyproject was
bumped to 0.4.3 (#179); regenerate so the two agree. No runtime deps added
(black stays in the test dependency group, not runtime).

* feat(python): add get_callsites_for batch accessor (#180 item 3)

Batch call-site fetch keyed by owning signature, the last of the four bulk
accessors from #180. One projected Cypher statement on the Neo4j backend (an
OPTIONAL MATCH over PY_HAS_CALLSITE so an existing callable with no call sites
still gets an empty-list entry, matching the in-process backend); one
symbol-table walk in-process. Added to the ABC, both backends, and the facade,
with offline and Neo4j-parity test coverage.

Minor release: new backward-compatible API since v1.2.0.

- Python facade bulk/projected accessors (get_callables_overview,
  get_method_bodies, get_decorated_callables, get_callsites_for) + the
  PyCallableOverview model (#181).
- TypeScript tsc_only toggle (TSCodeAnalyzerConfig) and synthesized anonymous
  callables (TSSynthesizedCallable, get_synthesized_callables) (#179).
- Neo4j Python backend reuses a single read session.
- codeanalyzer-typescript 0.4.0 -> 0.4.3.
