feat(hotpath): fill code-extraction extract/parse gaps

Gap-fill instrumentation for crates/tracedecay-code-extraction (HP-extract) only. Before this PR, 2 of 120 files carried hotpath sites (src/hotpath_observe.rs gauges, src/redundancy.rs two measures); all 51 *_extractor.rs files had zero spans. This adds #[hotpath::measure] to the uniform per-language entry points — trait extract / extract_parsed and inherent extract_tree / parse_source — giving per-language span breakdowns nested under the existing file-level code_extraction.parse_file / code_extraction.traverse_file spans.

• 191 new measure sites across 51 files, attributes only, zero behavior change.
• Labels follow code_extraction.<lang>.<verb> with verbs extract, extract_parsed, extract_tree, parse_source.
• No Cargo.toml or workspace feature changes; macros no-op without --features hotpath, and hotpath* features remain excluded from default/production.
• Fine-grained visit_* helpers, getters, Display impls, and tests are untouched.
• Existing measure sites (hotpath_observe.rs, redundancy.rs) left intact.
• Delegation targets (inherent extract/extract_batch bodies called by the trait extract) were deliberately not annotated to avoid double-counting the same work.

Verified: cargo check -p tracedecay-code-extraction and cargo check -p tracedecay-code-extraction --features hotpath both pass.

Files touched, measure sites, new labels

Verb key per file: E = …extract, EP = …extract_parsed, ET = …extract_tree, PS = …parse_source. Files without an inherent extract_tree/parse_source (composite adapters and delegating extractors) get only the trait entry points.
