tree-sitter-odin grammar install + languages.yaml

Goal

Resolve the one open feasibility item — the tree-sitter-odin grammar — and install it (PyPI if available, else the koka source-build precedent in setup-parsers.sh), then complete the languages.yaml entry and pass the smoke validation.

Implementation Sketch

Resolve a maintained tree-sitter-odin grammar; if not on PyPI, add a clone + patch + pip install block to intel_repo/scripts/setup-parsers.sh mirroring the koka path (lines 57-86).
Complete languages.yaml odin: entry: grammar, grammar_version, extensions: [".odin"], query_families: [decls, calls, imports, impls], coverage_status, expected_error_rate, module_name/language_func if the package differs from defaults.
Run validate-parsers.py --smoke for odin (grammar loads + parses minimal source without crash).

Work Items

Resolve + install tree-sitter-odin (PyPI or koka-style source build).
Complete languages.yaml odin entry.
validate-parsers —smoke passes for odin.

Acceptance

validate-parsers —smoke loads the odin grammar cleanly (probe python3 intel_repo/scripts/validate-parsers.py --smoke, comparator exact-match, expected pass).
