revert PRs #93-#98; enforce strict-linear-DAG + mandatory directive verify (#100)

* revert: roll back PRs #93-#98 to pre-Lexical baseline

Reverts the entire chain of directive document UI work and the homepage redesign,
restoring the working tree to the state at 3679ceb (before c8b169d / PR #93).

PRs reverted:
- #93 c8b169d feat: Document UI for directive orchestration with Lexical editor
- #94 d6f01a6 fix: compilation error and warnings already merged via PR #93
- #95 5aa3faf fix: resolve compilation error and warnings in Rust backend
- #97 d513f93 feat: document UI with contract blocks, expandable logs, and interaction controls
- #96 6366941 feat: Redesign homepage with professional PC-98 styling
- #98 d1fdfb1 feat: revert broken directive PRs, re-implement Lexical document orchestrator

The directive Document UI experiments produced fragile output and merge artifacts;
follow-up commits in this PR change orchestration to favor strictly linear DAGs and
add goal/conflict verification so future runs do not require this kind of cleanup.

* feat(directive): strict-linear-DAG planning + mandatory `directive verify`

Tightens directive orchestration so the final PR almost never needs a hand-merge:

1. Planning prompts now strongly bias toward strictly linear DAGs.
   Parallel steps are reserved for genuinely independent work (e.g. disjoint
   modules); the default for "in doubt" is sequential. Linear chains inherit
   each previous step's worktree, so the final merge is typically just a
   rebase against the base branch.

2. New CLI command `makima directive verify` does a local in-memory
   `git merge-tree` of HEAD against `<remote>/<base>` and exits non-zero
   with a list of conflicting files if the PR would not merge cleanly.
   Pure-local — no API call, no working-tree mutation.

3. Completion / PR-creation prompts now mandate three pre-push checks:
   a. build (`cargo check` and/or `tsc --noEmit`),
   b. `makima directive verify --base <base_branch>` must exit 0, and
   c. an explicit goal-alignment self-check against the diff.
   The orchestrator is told NOT to push, create the PR, or call
   `makima directive update` until all three pass. Skipping any of them
   is documented as a directive failure.

The combination means that with a linear DAG the final PR-creation task
should almost never see a real conflict — when it does, that is treated as
a planning bug to escalate rather than something to paper over with
`-X theirs`.

* fix(frontend): TS errors pre-existing on master

- TaskSlideOutPanel: declare missing `selectedFileDiff` / `selectedFilePath`
  state hooks that were referenced everywhere but never created, and
  re-balance the JSX so the `<>...</>` fragment in the non-diff branch is
  closed (the previous indentation/braces would not parse).
- api.ts: add a `getWorktreeDiff` thin wrapper around `getTaskDiff` so
  TaskDetail's per-file click handler type-checks (the per-file slice is a
  future improvement; today both return the full task diff).
- WorktreeFilesPanel: remove unused `isClickable` local; the gating already
  reads `onFileClick` directly inline.

Run after revert: `npx tsc --noEmit` exits 0.
