Gsd docs update

<objective> Generate and update up to 9 documentation files for the current project. Each doc type is written by a gsd-doc-writer subagent that explores the codebase directly — no hallucinated paths, phantom endpoints, or stale signatures.

Flag handling rule:

• The optional flags documented below are available behaviors, not implied active behaviors
• A flag is active only when its literal token appears in $ARGUMENTS
• If a documented flag is absent from $ARGUMENTS, treat it as inactive
• --force: skip preservation prompts, regenerate all docs regardless of existing content or GSD markers
• --verify-only: check existing docs for accuracy against codebase, no generation (full verification requires Phase 4 verifier)
• If --force and --verify-only both appear in $ARGUMENTS, --force takes precedence </objective>

<context> Arguments: $ARGUMENTS

Available optional flags (documentation only — not automatically active):

• --force — Regenerate all docs. Overwrites hand-written and GSD docs alike. No preservation prompts.
• --verify-only — Check existing docs for accuracy against the codebase. No files are written. Reports VERIFY marker count. Full codebase fact-checking requires the gsd-doc-verifier agent (Phase 4).

Active flags must be derived from $ARGUMENTS:

• --force is active only if the literal --force token is present in $ARGUMENTS
• --verify-only is active only if the literal --verify-only token is present in $ARGUMENTS
• If neither token appears, run the standard full-phase generation flow
• Do not infer that a flag is active just because it is documented in this prompt </context>

<process> Execute the docs-update workflow from @$HOME/.claude/get-shit-done/workflows/docs-update.md end-to-end. Preserve all workflow gates (preservation_check, flag handling, wave execution, monorepo dispatch, commit, reporting). </process>
