docs: replace removed PySwarms search example with Nautilus/dynesty/emcee (search-extensibility A0c)

[Jammy2211]

Summary

Search-extensibility A0c part 2 (PyAutoLens#776), the downstream sweep of removed-search ghosts. docs/index.md no longer offers PySwarms as an example search; Nautilus, dynesty and emcee are named instead. Docs-only: no source change.

API Changes

None. Documentation and citation files only.

Test Plan

• Witness grep (pyswarms/multinest) over docs/, CITATIONS.* and config/non_linear/ is empty
• GitHub docs legs green (RTD is red on the known autonerves floor; judge from the GitHub legs)

Full API Changes (for automation & release notes)

Removed

• none

Added

• none

Migration

• none

Validation checklist (--auto run — plan was not pre-approved)

• Effective level: safe (header: safe, cap: docs@medium → safe)
• Plan: on the issue (docs: search documentation repair, downstream sweep (search-extensibility A0c part 2) #776), written at start, unmodified since
• Gate: tests 832 passed, 1 xfailed (full test_autolens, docs-only diff) · smoke n/a (docs-only, no script surface) · review CLEAN (Fable session over the Opus-written branch; witness basis-cited: the pyswarms/multinest grep over docs/, CITATIONS.* and config/non_linear/ of all nine repos is empty and autocti api/modeling.rst has no dead target; one finding resolved before PR-open: the HowTo claim "every start_here.py uses MultiStartProdigy" was false by grep (8/21 lens, 5/9 galaxy) and now reads "many of") · Heart STALE release validation incomplete: no rehearsal for current source
• Human: plan sound in hindsight?
• Human: diff matches plan (no scope creep)?
• Human: merge, amend, or reject — then log the outcome

Tier: glance — Witness passed → in-turn auto-merge on green under the human's 2026-10-08 --auto launch; one-command revert: git revert <merge-sha>.
