docs: Fix stale /catchup refs, add /landed to README workflow

Replace remaining /catchup references with /landed in openai.md,
update README from 3-command to 4-command workflow with /landed in
diagram/examples, annotate removed /catchup items in IMPLEMENTATION_PLAN.

 **Goal:** Add 3 slash commands for context restoration, security auditing, and pre-deployment checks.
 
 **Acceptance Criteria:**
-- [x] `/catchup` command restores context after /clear
+- [x] ~~/catchup command restores context after /clear~~ (removed: overlaps with /sync)
 - [x] `/security-audit` command runs 6-phase security scan with A-F grading
 - [x] `/ship` command runs 3-tier pre-deployment checklist
 - [x] All commands have frontmatter with `allowed-tools` and `description`
 - [x] tests/test_commands.py passes
 
 **Tasks:**
-- [x] Create `.claude/commands/catchup.md`
+- [x] ~~Create `.claude/commands/catchup.md`~~ (removed: replaced by /landed skill)
 - [x] Create `.claude/commands/security-audit.md`
 - [x] Create `.claude/commands/ship.md`
 - [x] Create tests/test_commands.py
