Refuse compressed note sections with typed unsupported-target semantics before framing or decoding, preserving stored-range checks and physical descriptor-offset provenance. Flutter retains independent build IDs with partial coverage when compressed notes are skipped. Verify the existing shared alignment fix with prefixed notes across classes and table kinds.

* fix(flutter): honor ELF note alignment when reading build IDs
* test(flutter): key shared note ranges by effective alignment
Cover a program and section declaration that share one note range: differing effective alignments (8 and 4) must both be read, while declarations that both normalize to four bytes (1 and 4) still share one read. 24-byte build IDs pad identically at both alignments, so only the range key decides the read count.
* fix(flutter): reject ambiguous mappings and bound ELF notes
Resolve PT_LOAD interpretations once for symbols and dynamic tables, including partial overlaps. Preserve equivalent mappings and leave conflicting or invalid alternate definitions unresolved.
Bound distinct nonempty ELF note ranges before retention and reads, deduplicate shared ranges, preserve observed build-ID candidates and report partial coverage on exhaustion. Correct shared verifier workspace ownership and structured Windows path assertions.
Addresses the two post-merge review findings on PR #1582. Validation: 147 focused cases across Linux, macOS Sonoma 14.8.9 and non-administrator Windows 11 build 26300.9457; real Gallery CLI/MCP checks on all three hosts; six compiler-produced ELF32/ELF64 hash-layout cases; static, docs, discovery and duplication checks. Full string-pool projections remain explicitly bounded.
* test(flutter): parse complete facts through named result schemas
