chore(voyage): S34 — V30 economy-profile self-declares experimental (uncalibrated Jaccard floor)

The economy profile's cross-tier Jaccard floor (0.55) rests on parked-synthetic
fixtures; empirical Step-17 calibration is v4.2-budget-gated ($60–120,
unauthorized). Fork resolved as label-not-calibrate: the experimental status,
previously prose-only in docs/profiles.md, now lives in the profile data and is
machine-checked. No new user-facing capability — honest labeling + a guard.

- lib/profiles/economy.yaml: add `experimental: true` (with rationale comment).
- lib/validators/profile-validator.mjs: recognize `experimental` as an OPTIONAL
  boolean; non-boolean → PROFILE_INVALID_ENUM. Absent ⇒ tier is stable
  (premium/balanced unaffected, profile_version stays 1.0 — additive).
- README.md + docs/operations.md + docs/profiles.md: flag the `economy` table
  row "⚠ Experimental (uncalibrated Jaccard floor)".
- tests/synthetic/profile-jaccard-calibration.md + analysis §6/§10 + backlog
  plan §S34: cross-reference the marker; mark V30/S34 done.

+5 tests (739 → 744, 742/2/0): economy declares experimental:true; premium and
balanced do not; validator rejects non-boolean experimental; every profile-doc
economy row is flagged; the flag tracks the calibration's parked-synthetic
status (must drop in the same change that lands real calibration).

Closes the balance backlog (4/4, S31–S34). claude plugin validate green.

`economy` is *strictly experimental* in v4.1. The cross-tier Jaccard
floor (0.55) is grounded in parked-synthetic fixtures, not empirical
runs (Step 17 calibration was deferred — see
`tests/synthetic/profile-jaccard-calibration.md`). If you observe
economy-plan quality regressions, fall back to `balanced`.
`economy` is *strictly experimental* in v4.1, and says so in the profile
data itself: `lib/profiles/economy.yaml` carries `experimental: true`. The
cross-tier Jaccard floor (0.55) is grounded in parked-synthetic fixtures, not
empirical runs (Step 17 calibration was deferred — see
`tests/synthetic/profile-jaccard-calibration.md`). The flag is pinned: it must
stay `true` while the calibration status is `parked-synthetic`, and must be
dropped in the same change that lands empirical calibration
(`status: empirical`). If you observe economy-plan quality regressions, fall
back to `balanced`.
