bug: no input suggestions for the second of two identical component includes

[X-Guardian]

Bug summary

When a .gitlab-ci.yml includes the same component URL (or the same local: template path) more than once, input-name completions only appear under the first occurrence. Triggering completion in the second include's inputs: block returns nothing.

Steps to reproduce

1. Open a .gitlab-ci.yml that includes the same component twice (see the snippet below).
2. Under the second include's inputs:, add a blank line indented to match the input keys.
3. Trigger completion (it should pop automatically, or press Ctrl+Space).
4. Observe the completion list.

Expected behavior

The second include offers the same input-name suggestions as the first — the component's inputs, minus any already present under that second include.

Actual behavior

The completion list is empty under the second include. Only the first occurrence offers suggestions.

Minimal .gitlab-ci.yml snippet

include:
  - component: $CI_SERVER_FQDN/group/project/markdown-lint@markdown-lint-1
    inputs:
      allow_failure: "false"
  - component: $CI_SERVER_FQDN/group/project/markdown-lint@markdown-lint-1
    inputs:
      # trigger completion here — returns nothing on the duplicate

Fixed by #207 — input-name completions now appear under the second of two identical component/local: includes. Merged to beta; ships in 0.16.0 (tracked in #208).
