Owner

Closes BUG-5

Stacked on #1 (intake). Part of ECO-EP1.

What

fingerprint.rs: stable fingerprints from normalized symbols (legacy hash suffix, generics, closure numbering removed), the top 5 non-noise frames (panic machinery, runtime and GLib main-loop frames are skipped), the source file without line numbers or crate versions, and the panic message with numbers and markers removed. Rules are versioned. Unsymbolicated frames fall back to module+offset (groups within one build, still correct).
Freezes use the live stack when the user included one; behavior reports and evidence-free freezes get no fingerprint and are left for the fuzzy step (BUG-6).
Clusters (migration 2): app, kind, fingerprint, title, status, first/last seen, count, distinct installs, per-version and per-OS-build counts, fixed_in, issue_key, merged_into (resolved on assignment). Deleting a report shrinks its cluster and per-version counts. Quarantined reports are never clustered.
Clustering runs on intake and a failure never loses the report (it is stored unclustered and logged).

Tests

10 fingerprint tests: normalization, noise, locations, messages, the same bug across versions/machines hashes the same, different bugs differ, offset/module fallback, only the top frames count, freeze via live stack, no-evidence cases.
4 HTTP integration tests: same bug from two versions/installs is one cluster (count, installs, versions, os builds, title), different bug is a separate cluster, quarantined and fingerprintless reports are unclustered, deleting shrinks the cluster.
clippy -D warnings clean.

feat: deterministic crash fingerprinting and clusters

check / check (push) Has been cancelled

Reports with stable evidence (panic/crash frames, location, message, or a
live stack for a freeze) are fingerprinted from normalized symbols (hash
suffixes, generics and closure numbers stripped, runtime/panic noise
skipped), source file without line, and the message with numbers removed.
The same bug therefore groups across versions and machines. Clusters track
count, distinct installs, per-version and per-OS-build counts and first/last
seen; deleting a report shrinks its cluster. Quarantined reports are not
clustered. Rules are versioned (RULES_VERSION).

feat: re-run fingerprinting over stored reports

check / check (push) Successful in 28s

Details

refingerprint_all recomputes fingerprints for every clean stored report,
moves those whose fingerprint changed under new rules, and prunes clusters
left empty unless a human acted on them. Satisfies the 're-runnable' part of
the normalization-rules requirement.
