Add programs.notmuch.settings for native INI configuration with list
values, and generate the configuration file from it.
The new.ignore, new.tags, maildir.synchronizeFlags, search.excludeTags,
and extraConfig options become deprecated aliases into settings.
Settings carry no static defaults: new.tags, new.ignore, and
maildir.synchronize_flags fall back to notmuch's identical defaults.
State versions before 26.11 keep search.exclude_tags = deleted;spam and
write database.path even without email accounts. Enabled email
accounts supply database.path, and notmuch-enabled accounts the user
identity. Null values and empty sections are omitted so a derived
value can be removed.
extraConfig no longer overwrites modeled values unconditionally: forced
definitions win and ordinary collisions fail. The release notes
describe the migration.
Mbsync, lieer, and mujmap now write settings.new.ignore directly, so
they do not trigger deprecation warnings.
`literalExpression` is intended just to signify code that needs to stay
a string that gets represented exactly as-is for docs. It has been
misused heavily and people get confused repeatedly on when or not to use
it because of the rampant misuse.
Allow a user to disable an email account by setting
`accounts.email.accounts.<name>.enable = false`. This is useful if
someone wants to configure email accounts globally but only use them in
certain circumstances.
Everywhere email account configuration is used, check if the account is
enabled before checking any attributes of the account.
Reduce maintenance burden and increase efficiency by automatically
importing modules following a specific convention.
