Split the monolithic dot-dispatcher.zsh (4,395 lines) into three
focused dispatchers:
- dots (~1,600 lines) - dotfile management
- sec (~1,500 lines) - secret management
- tok (~1,300 lines) - token management

Each dispatcher gets its own completion file and doctor subcommand.
Clean break with no deprecated aliases.

the appropriate new dispatcher (dots/sec/tok).

- e2e-dispatcher-split.zsh: 66 automated tests covering all 3
  dispatchers (dots/sec/tok), function existence, old function
  removal, shared helpers, files, and completions
- dogfood-dispatcher-split.zsh: interactive dogfooding with
  real-world command execution and user confirmation

The dots help now uses "MOST COMMON" and "IGNORE & HEALTH" headings
instead of "COMMON COMMANDS", "IGNORE PATTERNS", "REPOSITORY HEALTH".

Comprehensive sweep of 17 files replacing stale `dot` dispatcher
references with the new `dots`, `sec`, and `tok` commands across
README, CHANGELOG, guides, tutorials, architecture docs, and fixtures.

Runtime function calls, user-facing messages, help text, and the
interactive tutorial all still referenced the removed dot() function.
Updated tok-dispatcher (13 calls), g-dispatcher (6), work.zsh (3),
flow.zsh (1), keychain-helpers (~30 messages), secret-tutorial (~35
references), and dotfile-helpers comments.

Updated 7 test files and 5 internal docs to use dots/sec/tok instead
of the removed dot dispatcher. Preserves --dot flags and historical
migration references intentionally.

- Rename _dot_token_expiring → _tok_expiring and _dot_token_rotate →
  _tok_rotate across 4 doc files (19 occurrences)
