lrreverence d643444e88 🐛 fix: Normalize action tool name at lookup + cover assistants path
Follow-up to the multi-action domain collision fix. Addresses PR #12594
review feedback:

**Must-fix #1 — short-hostname lookup mismatch.** The toolToAction map
is keyed on the `_`-collapsed domain, but `agent.tools` and
`currentAction.tool` persist the raw `domainParser(..., true)` output,
which for hostnames ≤ ENCODED_DOMAIN_LENGTH is a `---`-separated string
(e.g. `medium---com`). Exact-match `Map.get()` missed those keys and
silently dropped the tool. Fix: normalize every incoming tool name
through a new `normalizeActionToolName` helper before the lookup in
`loadAgentTools`, `processRequiredActions`, and
`loadActionToolsForExecution`.

**Must-fix #2 — assistants path coverage.** `processRequiredActions`
received the same structural rewrite but had zero tests. Added a
regression test under `multi-action domain collision regression` that
drives two shared-hostname actions through the assistants path and
asserts each tool reaches its own request builder.

**Must-fix #3 — legacy encoding branch coverage.** The
`if (legacyNormalized !== normalizedDomain)` registration was never
exercised by any test. Added a test where `agent.tools` stores the
legacy-format name and asserts it still resolves.

**Should-fix #4 — DRY the registration loop.** Extracted
`registerActionTools({ toolToAction, functionSignatures,
normalizedDomain, legacyNormalized, makeEntry })`. All three call sites
now share the same key-building logic; the key template lives in one
place.

**Should-fix #5 — remove stale optional chaining.** In
`loadActionToolsForExecution`, `functionSignature?.description ?? ''`
became `functionSignature.description` — `sig` is always defined by the
iterator, matching the style of `loadAgentTools`.

**Should-fix #6 — drop unreachable `!requestBuilder` guard.** Entries
in `processRequiredActions` are now pre-built with
`requestBuilder: requestBuilders[sig.name]`, which `openapiToFunction`
always produces alongside the signature, so the guard is dead.

**Should-fix #7 — unwrap `actionSetsData`.** It now holds a bare
`Map` instead of `{ toolToAction }`; the sentinel `!actionSetsData`
check still works because `new Map()` is truthy.

Also added a short-hostname regression test
(`loadAgentTools resolves raw ---separated tool names`) that reproduces
Must-fix #1: it fails against the previous commit (0 create calls) and
passes with the normalization in place.

41 tests, all passing. The 3 new regression tests are under
`multi-action domain collision regression` and cover the assistants
path, the legacy encoding branch, and the short-hostname lookup path.
