shenlei f50495ad91 fix: CFI module — 11 issues from code review
Phase 1 (correctness):
- #1: rawValue changed from stored to computed property, eliminating stale cache risk
- #2: tokenSamples/textMarker unified to UTF-16 offsets, fixing emoji/CJK positioning
- #3: makeOffsetCFI now accepts optional contentPath parameter

Phase 2 (robustness):
- #4: Resolver uses fixed index access instead of last(where:) for manifest/spine steps
- #5: HTML comments and CDATA stripped before regex matching
- #6: Text assertion parser handles backslash escapes (\[ \] \)
- #7: Token matching uses prefix/suffix with length ratio constraints
- #8: makeOffsetRangeCFI validates startOffset <= endOffset

Phase 3 (code quality):
- #9: Shared internal nilIfEmpty extension in RDEPUBCFIUtilities.swift
- #10: RDEPUBCFIMap has markerByPath index dictionary for O(1) lookup
- #11: parseRange unified to use try (not try?) for parent parsing

Review fixes:
- Documented init(rawValue:) parameter is ignored (computed property)
- Fixed escape unescaping to handle \\ → \ correctly
- Lowered token minLength threshold from 4 to 2
