* refactor(config): remove legacy gcal top-level config key
Problem: the gcal migration shim silently accepted vim.g.pending = { gcal
= {...} } and copied it to sync.gcal, adding complexity and a deprecated
API surface.
Solution: remove the migration block in config.get(), drop the cfg.gcal
fallback in gcal_config(), delete the two migration tests, and clean up
the vimdoc references. Callers must now use sync.gcal directly.
* ci: fix
* fix(spec): remove duplicate buffer require in complete_spec
* docs(pending): reorganize vimdoc and fix incorrect defaults
Problem: sections were out of logical order — inline metadata appeared
before commands, GCal before its own backend framework, store resolution
duplicated and buried after health check. Two defaults were wrong:
default_category documented as 'Inbox' (should be 'Todo') and the gcal
calendar example used 'Tasks' (should be 'Pendings').
Solution: reorder all 21 sections into onboarding-first flow, add a
CONTENTS table with hyperlinks, fix both incorrect defaults in every
location they appeared, and remove the duplicate STORE RESOLUTION
section.
