chore: release v0.4.0

[tob-scott-a]

Release v0.4.0

Version bump and release-prep metadata for v0.4.0. No source-level changes — all features in this release already landed via #46–#53.

Changes in this PR

• Bump version 0.3.1 → 0.4.0 in pyproject.toml, src/trailmark/__init__.py, and uv.lock.
• uv.lock also picks up the span-based (P1W) exclude-newer cooldown form (the prior frozen absolute timestamp is replaced by uv's sentinel; the 1-week cooldown span is unchanged).
• Fix _VERSION_PATTERN in tests/test_kat_cli.py to normalize v-prefixed versions (\bv?\d+...), so the (vX.Y.Z) string in the CLI help description is tokenized. The no_command_help snapshot now stores <VERSION> and no longer needs manual churn each release.

What's new since v0.3.1 (already merged)

• 8 new language parsers: Move, Tact, FunC, Sway, Rego, Protobuf, Thrift, GraphQL.
• Proxy nodes for unresolved call targets and resolvable type refs (TYPE_USES edges).
• Generics support (TypeParameter, SPECIALIZES/RESOLVES_TO edges, generic_parameters()/type_references() APIs).
• Subgraph bridges (connect_subgraphs(), subgraph_edges()).
• Binary graph import (augment_binary, CORRESPONDS_TO edges).
• trailmark diagram CLI subcommand.
• Storage refactor: per-edge-kind cached projections + public rebuild_index().

Verification

• ruff check clean
• pytest: 1166 passed
• uv build: produces trailmark-0.4.0 sdist + wheel
• uv sync: lockfile fully resolved
