The previous guidance ("Use `_declared` suffix") was too simplistic and
caused incorrect code review feedback. The new guidance distinguishes
three traversal patterns based on analysis type:
- Per-definition analysis: contracts_derived + functions_declared
- Reachability analysis: contracts_derived + functions (needs inherited)
- Global deduplication: compilation_unit.functions directly
This prevents false negatives when reviewers suggest functions_declared
for detectors that require reachability analysis of inherited functions.

* perf: cache Literal.__str__ conversion for numeric types
Optimize Literal.__str__() by caching the result of convert_string_to_int()
during construction. This avoids repeated expensive conversions when the
same literal is stringified multiple times during detector execution.
Changes:
- Add module-level _NUMERIC_TYPES frozenset for O(1) type lookup
- Cache converted string in __init__ for numeric string types
- Skip caching when subdenomination is set (uses converted_value instead)
- Preserve original behavior for ElementaryType inputs (no conversion)
Benchmark: ~16% faster on optimism codebase (50.7s vs ~61s)

* fix: use lenient threshold for timing test on Windows
Windows has lower timer resolution (~15.6ms default) and time.sleep()
can return slightly early. Lower the assertion threshold from 0.01 to
0.005 to account for this variance.

* fix: address PR review feedback for Literal caching
- Add unit tests for Literal class covering caching behavior
- Restore comment explaining non-numeric type fallback path
- Note: test_timing.py threshold lowered for Windows timer resolution

- Testing guidelines
- Slither internals (APIs, traversal patterns, SlithIR/SSA, detector quality)
CONTRIBUTING.md additions:
- PR description guidelines
- Commit message conventions
- Markdown documentation standards
