nullkey 5adcedf170 refactor(cli): v0.3 cross-cutting cleanup
Cross-cutting findings surfaced by the branch-completion review.

Perf bug:
- Factory.Client closure was not memoized. Factory.ResolveKB internally
  calls f.Client() to resolve --kb name → id, then the command's RunE
  calls f.Client() again. Two SDK clients, two keyring reads, two
  AuthRetryTransport allocations per name-resolved invocation, with
  *independent* token state (a refresh in one was invisible to the
  other). Switched to sync.Once like Secrets already does.

Silent bug bait:
- cmdutil.NormalizeHost docstring claimed CodeInputMissingFlag for the
  empty case; code returned CodeInputInvalidArgument. Aligned doc to
  code (present-but-empty is a bad value, not a missing flag).

Agent contract gaps:
- Five user-facing subcommands lacked SetAgentHelp: auth login /
  logout / list / status and chat. Added concise strings with error-
  code call-outs so agents can branch without parsing human strings.

Helper extraction (≥3 callers):
- text.KnowledgeDisplayName(fileName, title, id) — byte-identical
  formatter that was in both cmd/doc/list.go and cmd/search/docs.go.
  Takes fields directly so internal/text stays SDK-free.
- cmdutil.WrapHTTP(cause, fmt, args...) *Error — replaces the
  `Wrapf(ClassifyHTTPError(err), err, ...)` pattern across 24 SDK
  call sites. Sed-driven migration; off-pattern shapes in chat.go
  (used streamErr) and cmdutil/kb.go (in-package) hand-edited.
  Contract test gains a comment update: post-migration the dominant
  pattern is WrapHTTP which the AST scanner skips entirely (only
  NewError/Wrapf selectors inspected); ClassifyHTTPErrorOutputs()
  bridge still covers the dynamic codes those paths can yield.

UX consistency:
- cmd/doc/list.go --page-size help now reads "Items per page
  (1..1000)" matching cmd/session/list.go. The bounds validation
  already enforced 1..1000; the help text was the last drift.

Comment-discipline sweep:
- Deleted the WHAT-only "*Options captures `weknora ...` flag state"
  docstring across 23 files (context, kb, auth, doc, session, search,
  chat, doctor, link). Where the line carried a real WHY clause
  (kb/delete, doc/delete, session/delete, kb/edit), kept the WHY and
  dropped only the leading WHAT phrase.
- Stripped third-party project-name attribution from inline comments
  and one user-visible flag-help string across ~40 files in cli/cmd
  and cli/internal (plus 4 test-file comments). Removed phrases like
  "Mirrors `gh X`", "borrowed from lark-cli", "kubectl-style",
  "gcloud `--project`", "Stripe pattern", and the embedded GitHub
  URLs pointing at those projects. Behavioral descriptions and the
  WHY behind each comment are preserved; only the upstream-name
  attribution is gone. Inspiration / north-star references belong in
  cli/AGENTS.md (the design doc) and commit messages, not scattered
  through every file.

  Triggered by an audit round that surfaced several false / fragile
  parity claims (e.g. "Mirrors `gh repo edit`" — gh repo edit has no
  --name flag; "matches gcloud `--project` id-or-name" — gcloud's
  --project accepts ID only). Rather than fix them one by one, the
  whole category of in-comment external-project references was
  stripped uniformly.
