Completion refresh misses newly generated completions

[ss-o]

Summary

Completions that are present on disk and visible in zi clist can still be unavailable to Zsh immediately after install/refresh.

This shows up most clearly with completions generated by atclone, such as the case reported in the organization discussion:
https://github.com/orgs/z-shell/discussions/334

User-visible behavior

A plugin/snippet installs or generates a completion file like _cscli.

• zi clist shows the completion as installed
• the completion file exists in ${ZI[COMPLETIONS_DIR]}
• but completing cscli <TAB> does nothing
• zi compinit / a full compinit rebuild makes it start working

Example configuration

zi wait='1b' lucid for \
  atinit='export PIPENV_SHELL_FANCY=true' \
    OMZP::pipenv \
  light-mode \
    as="completion" id-as="cscli/completion" has="cscli" \
    blockf \
    atclone="cscli completion zsh > _cscli" \
    atpull="%atclone" z-shell/null

Root cause

After completion mutations, Zi refreshes with compinit -C via .zi-compinit 1 1.

-C reuses the existing dump instead of rebuilding completion mappings, so newly added/generated completion files can remain absent from _comps even though they were symlinked correctly and appear in zi clist.

I verified this with a minimal repro:

1. initialize completion system
2. add a new _bar completion file after the initial dump exists
3. run the current refresh path (.zi-compinit 1 1)
4. _comps[bar] is still missing
5. run a full .zi-compinit 1
6. _comps[bar] is registered

Suspected fix

Any path that changes installed/enabled/disabled completions should rebuild compinit state without -C.

Relevant call sites include:

• zi.zsh
• lib/zsh/install.zsh
• lib/zsh/autoload.zsh

In practice, the stale refresh paths are the places currently calling .zi-compinit 1 1 immediately after completion install/remove/enable/disable/update flows.

Notes

This is separate from whether the completion file itself is valid. The failure mode here is that Zi's refresh path can leave new completions invisible until a full compinit rebuild happens.
