rustperf rule ids (slugs)

Canonical ids are slugs only. Numerics from the old map are historical and not accepted.

Slug
`rs-alloc-hot`
`rs-println-hot`
`rs-format-rebind-hot`
`rs-collect-vec-hot`
`rs-map-new-hot`
`rs-regex-new-hot`
`rs-file-open-hot`
`rs-clock-hot`

See also root rule-id-map.

Renamed 2026-10-27 (tombstone old; never reuse)

Default --scope all (or kit-equivalent). Old *-in-loop ids misled tools/models; they are tombstoned under evidence/_removed/.

Old slug	New slug
`rs-alloc-in-loop`	`rs-alloc-hot`
`rs-clock-in-loop`	`rs-clock-hot`
`rs-collect-vec-in-loop`	`rs-collect-vec-hot`
`rs-file-open-in-loop`	`rs-file-open-hot`
`rs-format-rebind-in-loop`	`rs-format-rebind-hot`
`rs-println-in-loop`	`rs-println-hot`
`rs-regex-new-in-loop`	`rs-regex-new-hot`
`rs-map-new-hot`	`rs-map-new-hot`

Removed

rs-string-plus-in-loop — large fill about 1.00×; see evidence/_removed/
rs-vec-no-capacity — large fill about 1.00× and about 1.05× bytes; see evidence/_removed/
