Gergo Magyar ed0c0b9a1d fix(group)!: honour --exact-only, drop inert --allow-stale, report every matching stage
Addresses the review findings on #3020, all of which are the same defect the PR
itself is about: group-sync surface that describes behaviour the pipeline does
not have.

`exactOnly` was inert in exactly the way `skipEmbeddings` was — declared on
`SyncOptions`, threaded through the CLI and the MCP tool, and read by nothing —
and strictly worse, because the stage it promised to suppress DOES run and DOES
write `matchType:'wildcard'` links into contracts.json and the bridge, which
`group impact` and cross-repo `trace` then traverse. It is now honoured rather
than deleted: unlike the never-built BM25/embedding stages, the stage it names
exists, so the flag describes a real choice. The substituted result is
`{ matched: [], remaining: unmatched }`, not an empty result — `wildcard.remaining`
IS `SyncResult.unmatched`, so skipping the stage has to leave its input unmatched
rather than dropping it from the count an operator reads.

`allowStale` had no such stage to gate: `syncGroup` emits no stale warning at any
point (the `checkStaleness` call lives in `groupStatus`, a different path), so it
is removed under the same rationale as `skipEmbeddings`.

`group sync` now prints every matching stage instead of `exact` alone. The old
block printed a `Matching cascade:` header and counted only exact links while the
next line reported `result.crossLinks.length` — which also includes `manifest` and
`wildcard` — so for any group with those the two numbers disagreed with nothing on
screen explaining why. Counting is an exhaustive `Record<MatchType, number>`, so a
new MatchType fails the build here instead of going silently uncounted, and reads
through `?? 0` so a legacy registry carrying a removed matchType prints an honest
count rather than `NaN`.

Also: the MCP `group_sync` description no longer omits the wildcard stage that
always runs, `exactOnly`'s description no longer refers to a "cascade", and
bench/cross-repo-trace/verify.mjs no longer generates the removed threshold keys
into a fresh group.yaml.

Tests: `sync-exact-only.test.ts` pins both directions of the gate (mutation-verified:
removing the gate, or returning `remaining: []`, both go red). `group-tools.test.ts`
pins that the MCP schema dropped `skipEmbeddings` and kept `exactOnly`.
`group-cli.test.ts` pins that both removed flags are rejected, with `--exact-only`
as an accepted-flag control. `config-parser.test.ts` now pins that legacy keys are
PRESERVED (measured, not assumed) rather than only that parsing does not throw.

The type narrowing's fallout in test files is cleared: `tsc -p tsconfig.test.json`
is 987 errors at head against 987 measured on origin/main, with the two error sets
identical — zero net, zero new, zero masked.

Verification: `tsc --noEmit` exit 0; prettier clean; eslint 0 errors (2 warnings,
both pre-existing on base); 69 test files / 1169 tests green across
test/unit/group, test/integration/group, tools, cli-i18n and cli-index-help.
